stoney backup Service Software

The stoney backup Service comes along with multiple scripts which help you to manage and monitor your backup server and accounts:

We use rsnapshot - remote filesystem snapshot utility for the actual snapshots and a handful of wrapper scripts, that do things like:

  • Read the users and their settings from the LDAP directory.
  • Execute rsnapshot according to the users settings.
  • Write the backup quotas backup (incoming), iterations (.snapshots) and free space to the users local backupSize file and update the LDAP directory.
  • Inform the reseller, customer or user (depending on the settings in the LDAP directory) via mail, if the quota limit has been reached.
  • Depending on the users settings in the LDAP directory, warning mail will be sent to the reseller, customer or user, if a backup was not executed on time.

All these scripts are installed to /usr/libexec/backup-utils/ by the sys-apps/sst-backup-utils package (see backup-utils). The source code can be found on github

writeAccountSize.pl

This script is installed to /usr/libexec/backup-utils/writeAccountSize.pl by the sys-apps/sst-backup-utils package and does the following: @PAT: Please add a link to the current Git repository. --Chrigu (talk) 10:15, 19 June 2014 (CEST)

  • Calculates the used disk space (backup and iterations) for a given account and writes the corresponding values to:
    1. The LDAP backend (used by the selfcare webinterface to display quota information):
      • Backup space used (sstBackupSize): The disk space the account uses for the backup itself (disk space used under the incoming folder of the users chroot-home directory)
      • Snapshot space used (sstIncrementSize): The disk space the account uses for the iterations (disk space under the .snapshot folder of the users chroot-home directory)
    2. The file etc/backupSize of the accounts chroot (used by the Sepiola Online Backup client):
  • Checks if the user and/or reseller must be notified that there is no more disk space left for the given account
    • Checks if the notification flag was passed, if not no notification will be triggered
    • Calculates the used disk space (backup and iterations) in percentage
    • Reads the notification threshold value from the LDAP backed
    • If the disk space used (in percentage) is bigger than the value retrieved from the LDAP backend start the notification process with
      • Product: Given account UID
      • Service: Backup
      • Problem: Quota

NAME
    writeAccountSize.pl

DESCRIPTION
    This Script gets quota information from filesystem, size of incoming and
    snapshots directories, write the data to a file and the LDAP backend and
    sends an e-mail message for each account that is over quota to users
    e-mail address (from ldap directory) if notification flag is passed.

    The configuration file for this script is stored in the backup-utils
    configuration directory (/etc/backup-utils/) and is called
    writeAccountSize.conf.

    The script needs access to the quota program to get quota information.
    The script needs ldap access to get users e-mail address and quota
    information. The script uses syslog for logging purposes.

    Command Line Interface (CLI) parameters:

    -C configfile
        The configuration file.

    -U uid
        The user id.

    -n notification
        Start notification process if quota threshold is reached

    -d debug
        Turns the debug mode on.

    -h help
        This online help.

Everything seems to be working fine!

snapshot.pl

This script is installed to /usr/libexec/backup-utils/snapshot.pl by the sys-apps/sst-backup-utils package and does the following:

  • Read interval parameter value passed
    • The interval parameter value can be daily, weekly, monthly (or yearly)
  • Find all backup active accounts for which the rsnapshot command must be executed (depending on the given interval)
    • Filter to find these accounts: (&(sstBackupInterval<INTERVAL>=*)(sstIsActive=TRUE)) for example for the daily rsnapshot the filter is (&(sstBackupIntervalDaily=*)(sstIsActive=TRUE))
      • In other words this means: Get me all acounts that have for sstBackupInterval<INTERVAL> a value defined AND sstIsActive is set to "TRUE"
  • According to the interval given and the account UID calculate the rsnapshot command for all these accounts
    • For example
      • Account UID: 4000000
      • Interval: daily
      • Resulting rsnapshot command: /usr/bin/nice -n 19 /usr/bin/rsnapshot -c /etc/rsnapshot/rsnapshot.conf.4000000 daily (if you use the configuration below)
  • Execute all these commands
    • Use controlled parallel execution, you can specify how many commands can be executed in parallel (see configuration below)
  • Pod documentation: 
NAME
    snapshot.pl

DESCRIPTION
    This script gets all active online backup accounts from the LDAP backend
    for which the rsnapshot process for the given interval must be executed.
    According to these accounts and the given interval, the commands to be
    executed are generated and finally executed. The commands can be
    executed in parallel, however there is a limit defined in the
    configuration file which limits the amount of parallel running
    processes.

USAGE
    ./snapshot.pl --interval interval [--debug] [--help]

OPTIONS
    --interval/-i interval
        Specifies the rsnapshot interval (can be hourly, daily, weekly,
        monthly or yearly)

    --debug/-d
        Turns on debug mode

    --help/-h
        Shows this help

        Parallel::ForkManager;
        Time::Stopwatch;

Configuration

There are two things to do in this step:

  • Configure the rsnapshot root directory
  • Configure the snapshot.pl script itself

rsnaphot configuration directory

The users individual rsnapshot configurations are stored under /etc/rsnapshot. Please make sure, that the directory exists: 

ls -al /etc | grep rsnapshot

drwx------  2 root   root      64 30. Aug 20:20 rsnapshot

If not, create it: 

mkdir /etc/rsnapshot
chmod 700 /etc/rsnapshot

snapshot.pl Configuration

The snapshot.pl script is responsible for the execution of rsnapshot according to the users settings. 

/etc/backup-utils/snapshot.conf 

[General]
MaxParallelProcesses = 5
Rsnapshot_command = /usr/bin/nice -n 19 /usr/bin/rsnapshot  -c /etc/rsnapshot/rsnapshot.conf.%uid% %interval%

[LDAP]
Host = ldaps://ldapm.tombstone.ch
Port = 636
User = cn=Manager,dc=stoney-cloud,dc=org
Password = <Password>
CA_Path = /etc/ssl/certs
Accounts_Base = ou=accounts,ou=backup,ou=services,dc=stoney-cloud,dc=org

Legend: At runtime the following placeholders are replaced as follows

  • %uid%: The backup account and login uid as a numeric number. For example: 4000205.
  • %interval%: The backup level to be executed. Possible values are hourly, daily, weekly, monthly and yearly.

Tests

Before adding the necessary cronjob entries, we need to make sure, that we've configured the snapshot.pl script correctly: 

/usr/libexec/backup-utils/snapshot.pl --interval daily -d

If everything worked as planned, you should receive feedback looking roughly like: 

INFO:  Starting rsnapshot for interval daily with maximum 5 parallel processes

INFO:  Executing snapshot for 4000080

INFO:  Executing snapshot for 4000079

INFO:  Snapshot process for 4000079 finished in 0.18 seconds with status 0

INFO:  Snapshot process for 4000080 finished in 0.19 seconds with status 0

INFO:  rsnapshot for all backups done. Took 0.24 seconds

Just to make sure, that everything did work out fine, execute writeAccountSize.pl again: 

/usr/libexec/backup-utils/writeAccountSize.pl -U 4000080 -d

As you can see, the total used space has risen to 39.0625.

Cronjobs

After making sure, that everything worked as planned, you can update your crontab entry: 

crontab -e

...
# Rsnapshot for all users
30 22 * * * /usr/libexec/backup-utils/snapshot.pl --interval daily
15 22 * * sun /usr/libexec/backup-utils/snapshot.pl --interval weekly
00 22 1 * * /usr/libexec/backup-utils/snapshot.pl --interval monthly
...
  • TBD: Maybe this is not optimal if there is a lot of data to rotate. In this case, it might be that for example weekly and daily snapshot both run at the same time what might lead to strange results.
  • Workarounds:
    • Simple/short version: Instead one could create another wrapper script which is called everyday and does some simple logic:
    • Is today the first day of a month?
      • Yes: Is today sunday?
        • Yes: Execute monthly then weekly then daily rsnapshots using the snapshot.pl script (but wait for each interval to finish before starting the next)
        • No: Execute monthly then daily rsnapshots using the snapshot.pl script (but wait for monthly interval to finish before starting the daily)
      • No: Is today sunday?
        • Yes: Execute weekly then daily rsnapshots using the snapshot.pl script (but wait for weekly interval to finish before starting the daily)
        • No: Execute daily rsnapshots using the snapshot.pl script
    • Complex/long version: Adapt the snapshot.pl script and call it every day without interval parameter. The script does the logic described above.

This avoids the above mentioned collision

(Complex) / short version: rule via cronjobs: 

# Rsnapshot for all users
30 22 * * 1-6 [ $( date +\%d ) -gt 1 ] && /usr/libexec/backup-utils/snapshot.pl --interval daily
15 22 * * 7 [ $( date +\%d ) -gt 1 ] && /usr/libexec/backup-utils/snapshot.pl --interval weekly && /usr/libexec/backup-utils/snapshot.pl --interval daily
00 22 1 * * /usr/libexec/backup-utils/snapshot.pl --interval monthly && /usr/libexec/backup-utils/snapshot.pl --interval weekly && /usr/libexec/backup-utils/snapshot.pl --interval daily
...

scheduleWarning.pl

This script is installed to /usr/libexec/backup-utils/scheduleWarning.pl by the sys-apps/sst-backup-utils package and does the following:

  • The basic task of this script is simple: For the given account
    • Check if the planned backups were started
      • If not, start the notification process with
        • Product: Given account UID
        • Service: Backup
        • Problem: Schedule
    • Check if the planned backups finished successfully
      • If not, start the notification process with
        • Product: Given account UID
        • Service: Backup
        • Problem: Unsuccessful

As the backup clients distributed by stepping stone GmbH upload metadata XML before (scheduling information and start time) and after (end time and backup status) the actual backup, the scheduleWarning.pl script is able to verify whether or not a planned backup has been executed and whether or not the backup was successful.

  • Pod documentation 
NAME
    scheduleWarning.pl

DESCRIPTION
    This script tests whether a planed backup was successful or not. There
    are two different typs of failure.

    1. The Backup did not start
        The first type of error is that a backup is scheduled for YYYY-MM-DD
        at HH:MM, but the backup don't start at this specified time. A
        possible reason could be that the computer was shut down.

    2.The backup was not successful
        The second type of error is that a backup started as scheduled but
        did not finish successfully. There are different reasons for this
        error.

    If a backup wasn't successful the script checks which type of error
    occured. It reads the XML files which are stored on the server and
    compares the given information. If the error is detected, the script
    stats the norification process with the information of the error.

    If a user has more than one computer backed-up, the script tests one
    computer after the other. The mail(s) sent by the programm also
    contain(s) the information which computer is affected.

OPTION
    -U uid
        The -U option is required to run the script, it indicates for which
        uid the script is executed.

checkBackups.pl

This script is installed to /usr/libexec/backup-utils/writeDate.pl by the sys-apps/sst-backup-utils package. It is a wrapper around the above mentioned writeAccountSize.pl and scheduleWarning.pl scripts (if you configure it accordingly).

  • As mentioned the script is a wrapper for calling the quota and scheduler information scripts:
    • It gets all active backup accounts from the LDAP directory
    • According to the CLI parameters passed it calles for all these accounts:
      • The quota checking script (this script can be defined in the configuration file, see configuration section below)
      • The scheduler checking script (this script can be defined in the configuration file, see configuration section below)
  • Pod documentation: 
NAME
    checkBackups.pl

DESCRIPTION
    This script processes all active backup accounts and checks (according
    to the command line options) the quota and/or the scheduled backups for
    the given accounts.

    The script uses syslog for logging purposes.

    Command Line Interface (CLI) parameters:

OPTIONS
    --schedule/-s
        Checks schedule information by calling the defined script

    --quota/-s
        Checks the quota values by calling the defined script

    --notify/-n
        Passes the notify flag to the called scripts

USAGE
    ./checkBackups.pl [--quota] [--schedule] [--notify]

    ./checkBackups.pl --quota
        Checks and writes the quota for all active backup accounts. The user
        and/or reseller will NOT be informed if any quota threshold is
        reached

    ./checkBackups.pl --quota --notify
        Checks and writes the quota for all active backup accounts. The user
        and/or reseller will be informed if any quota threshold is reached.

    ./checkBackups.pl --schedule
        Checkes all active backup account if the scheduled backup was
        executed and successful. The --schedule option will allways trigger
        a notification mail to the user and/or reseller.

    ./checkBackups.pl --schedule --quota
        Checks both, quota and schedule, for all active backup accounts.

    2013-11-19 pat.klaey@stepping-stone.ch Added options to be able to check
    quota, schedule or both in one run

INCORPORATED CODE
    Incorporated code with use:

        warnings;
        strict;
        Getopt::Long;
        Sys::Syslog;
        Cwd 'abs_path';
        File::Basename;
        PerlUtil::LDAPUtil;
        PerlUtil::Logging;

Configuration

In the configuration you have to define two simple things:

  1. Which script to call for quota checks and scheduler checks
  2. How to access the LDAP backend 
/etc/backup-utils/checkBackups.conf

[Scripts]
CheckQuotaScript = /usr/libexec/backup-utils/writeAccountSize.pl
CheckScheduleScript = /usr/libexec/backup-utils/scheduleWarning.pl

[LDAP]
Server = ldaps://ldapm.tombstone.ch
Port = 636
Username = cn=Manager,dc=stoney-cloud,dc=org
Password = <PASSWORD>
AccountBase = ou=accounts,ou=backup,ou=services,dc=stoney-cloud,dc=org

Cronjobs

As you can pass the notification flag to the scripts, you can call the quota script say all 10 minutes. This makes sense if followed the configuration section, as the writeAccountSize.pl script writes the quota values to the LDAP backend which will then be visible in the selfcare webinterface. Like that you have a more or less up to date quota representation in the selfcare webinterface. On the other side, you don't want to send notification mails to the user every 10 minutes. It might be enough to send them once a day, so the cronjobs may look like: 

# Check backups
15 12 * * * /usr/libexec/backup-utils/checkBackups.pl --schedule --quota --notify

# Write quota values every 10 minutes
*/10 * * * * /usr/libexec/backup-utils/checkBackups.pl --quota

ResellerBackupBilling.pl

This script is installed to /usr/libexec/backup-utils/writeDate.pl by the sys-apps/sst-backup-utils package. The pod documentation says all what needs to be said about this script.

  • Pod documentation 
NAME
    ResellerBackupBilling.pl

DESCRIPTION
    This script processes the reseller with the passed UID and creates a
    very simplistic backup-billing overview which then is sent to the
    address specified in the configuration file. The billing overview
    contains all backup accounts which belong to the given reseller as well
    as their quota. According to the billing plan specified in the
    configuration file, the script also calculates the price for each backup
    account.

    The script uses syslog for logging purposes.

    Command Line Interface (CLI) parameters:

OPTIONS
    --reseller/-r UID
        Process the reseller with this UID

    --debug/-d
        Turn on debug mode

    --help/-h
        Display this help

USAGE
    ./ResellerBackupBilling.pl --reseller UID [--debug] [--help]

    ./ResellerBackupBilling.pl --reseller 2000000
        This processes the reseller with the UID 200000 and sends the
        billing overview to the address specified in the configuration file

        PerlUtil::Mail;
        Number::Format;
        File::Basename;
        Cwd 'abs_path';

Configuration

You have to configure basically three things:

  1. How to access the LDAP directory (similar to the other backup-util scripts)
  2. Define a pricing schema
    • Define a base price for an account
    • Define a GB price
    • The total price for each account will finall be: base price + ( quota in GB * GB price )
  3. How to send the mail
    • You need to enter a valid (outgoing) mail server and corresponding port
    • User and password to authenticate on the mail server
    • A valid recipient (typically the company’s backoffice address) and sender 
/etc/backup-utils/ResellerBackupBilling.conf

[LDAP]
Server = ldaps://ldapm.tombstone.ch
Port = 636
Username = cn=Manager,dc=stoney-cloud,dc=org
Password = <Password>
AccountBase = ou=accounts,ou=backup,ou=services,dc=stoney-cloud,dc=org
CustomerBase = ou=customers,dc=stoney-cloud,dc=org
ResellerBase = ou=reseller,dc=stoney-cloud,dc=org

[Pricing]
AccountBasePrice = 5.00
AccountGBPrice = 0.50

[Mail]
Server = <Mail-Server>
Port = 587
Username = <Sender-Email-Address>
Password = <Password>
To = <Backoffice>
From = Billing Script <E-Mail-Address>

writeDate.pl

This script is installed to /usr/libexec/backup-utils/writeDate.pl by the sys-apps/sst-backup-utils package. This is a very simple script, it simply writes the current date and time to a file on the backup server before the rsnapshots rotates the backup. This date is used by the Sepiola Online Backup Client to display the iterations and their dates.

  • Pod documentation: 
NAME
    writeDate.pl

DESCRIPTION
    This script writes the current date and time into the file for each
    backup before the rsnapshots rotates the backup. This information is
    used by the Sepiola Online Backup Client.

    The configuration file for this script is stored under
    /etc/backup-utils/writeDate.conf

    The script uses syslog for logging purposes.

    Command Line Interface (CLI) parameters:

    -C configfile
        The configuration file.

    -U uid
        The user id.

    -d debug
        Turns the debug mode on.

    -h help
        This online help.

USAGE
    writeDate.pl [-C configuration_file] [-U uid] [-d debug] [-h help]

rsnapshot wrapper bash scripts

There are two rsnapshot wrapper scripts (these are bash scripts), they are installed by the sys-apps/sst-backup-utils package:

  • /usr/libexec/backup-utils/rsnapshotPreExecWrapper.sh
    • This script is executed before the rsnapshot process and simply calls the writeDat.pl script.
  • /usr/libexec/backup-utils/rsnapshotPostExecWrapper.sh

Note: These scripts do not need any configuration.
