Abstract

This document describes server setup for the stoney cloud (Online) Backup service, built upon the Gentoo Linux distribution.

Overview

After working through this documentation, you will be able to set up and configure your own (Online) Backup service server.

Software Installation

Requirements

A working stoney cloud installation.

Keywords & USE-Flags

For a full OpenLDAP directory installation:

echo "net-nds/openldap overlays perl sasl" >> /etc/portage/package.use

For a minimal OpenLDAP directory installation (just the necessary tools):

echo "sys-auth/nss-pam-ldapd sasl" >> /etc/portage/package.use
echo "sys-auth/nss-pam-ldapd ~amd64" >> /etc/portage/package.keywords
echo "net-nds/openldap ~amd64" >> /etc/portage/package.keywords
echo "sys-fs/quota ldap" >> /etc/portage/package.use

For the prov-backup-rsnapshot daemon

echo "dev-perl/Net-SMTPS ~amd64" >> /etc/portage/package.keywords
echo "perl-core/Switch ~amd64" >> /etc/portage/package.keywords

To build puttygen only without X11 (ebuild currently from our overlay, see Gentoo Bug #482816):

echo "net-misc/putty ~amd64" >> /etc/portage/package.keywords
echo "net-misc/putty -gtk" >> /etc/portage/package.use

Software Configuration

Quota

32-bit Project Identifier Support

We need to enable 32-bit project identifier support (PROJID32BIT feature) for our naming scheme (uid numbers larger than 65'536):

mkfs.xfs -i projid32bit=1 /dev/vdb1

Mount

Make sure, that you have user quota (uqota) and project quota (pquota) set as options on the chosen mount point in /etc/fstab. For example:

/dev/vdb1               /var/backup     xfs             noatime,uquota,pquota   0 0

Verify

Some important options for xfs_quota:

-x: Enable expert mode.
-c: Pass arguments on the command line. Multiple arguments may be given.

Remount the file system /var/backup and check, if /var/backup has the desired values:

xfs_quota -x -c state /var/backup

As you can see (items marked bold), we have achieved our goal:

User quota state on /var/backup (/dev/vdb1)
  Accounting: ON
  Enforcement: ON
  Inode: #131 (3 blocks, 2 extents)
Group quota state on /var/backup (/dev/vdb1)
  Accounting: OFF
  Enforcement: OFF
 Inode: #809717 (1 blocks, 1 extents)
Project quota state on /var/backup (/dev/vdb1)
  Accounting: ON
  Enforcement: ON
  Inode: #809717 (1 blocks, 1 extents)
Blocks grace time: [7 days 00:00:30]
Inodes grace time: [7 days 00:00:30]
Realtime Blocks grace time: [7 days 00:00:30]

User Quotas

Adding a User Quota

Set a quota of 1 Gigabyte for the user 4000187 (the values are in kilobytes, so 1048576 kilobyte are 1024 megabytes which corresponds to 1 gigabyte):

xfs_quota -x -c 'limit bhard=1048576k 4000187' /var/backup

Or in bytes:

xfs_quota -x -c 'limit bhard=1073741824 4000187' /var/backup

Read the quota information for the user 4000187:

xfs_quota -x -c 'quota -v -N -u 4000187' /var/backup

/dev/vdb1                    0          0    1048576   00 [--------] /var/backup

If the user has data in the project, that belongs to him, the result will change:

/dev/vdb1               512000          0    1048576   00 [--------] /var/backup

Modifiying a User Quota

To modify a users quota, you just set a new quota (limit):

xfs_quota -x -c 'limit bhard=1048576k 4000187' /var/backup

Read the quota information for the user 4000187:

xfs_quota -x -c 'quota -v -N -u 4000187' /var/backup

/dev/vdb1                    0          0    1048576   00 [--------] /var/backup

If the user has data in the project, that belongs to him, the result will change:

/dev/vdb1               512000          0    1048576   00 [--------] /var/backup

Removing a User Quota

Removing a quota for a user:

xfs_quota -x -c 'limit bhard=0 4000187' /var/backup

The following command should give you an empty result:

xfs_quota -x -c 'quota -v -N -u 4000187' /var/backup

Project (Directory) Quotas

Adding a Project (Directory) Quota

The XFS file system additionally allows you to set quotas on individual directory hierarchies in the file system that are known as managed trees. Each managed tree is uniquely identified by a project ID and an optional project name. We'll use the following values in the examples:

project_ID: The uid of the online backup account (4000187).
project_name: The uid of the online backup account (4000187). This could be a human readable name.
mountpoint: The mountpoint of the xfs-filesystem (/var/backup). See the /etc/fstab entry from above.
directory: The directory of the project (187/4000187), starting from the mountpoint of the xfs-filesystem (/var/backup).

Define a unique project ID for the directory hierarchy in the /etc/projects file (project_ID:mountpoint/directory):

echo "4000187:/var/backup/187/4000187/home/4000187" >> /etc/projects

Create an entry in the /etc/projid file that maps a project name to the project ID (project_name:project_ID):

echo "4000187:4000187" >> /etc/projid

Set Project:

xfs_quota -x -c 'project -s -p /var/backup/187/4000187/home/4000187 4000187' /var/backup

Set Quota (limit) on Project:

xfs_quota -x -c 'limit -p bhard=1048576k 4000187' /var/backup

Check your Quota (limit)

xfs_quota -x -c 'quota -p 4000187' /var/backup

Check the Quota:

-v: increase verbosity in reporting (also dumps zero values).
-N: suppress the initial header.
-p: display project quota information.
-h: human readable format.

xfs_quota -x -c 'quota -v -N -p 4000187' /var/backup

/dev/vdb1                    0          0    1048576   00 [--------] /var/backup

If you copied data into the project, the output will look something like:

/dev/vdb1               512000          0    1048576   00 [--------] /var/backup

To give you an overall view of the whole system:

xfs_quota -x -c report /var/backup

User quota on /var/backup (/dev/vdb1)
                               Blocks                     
User ID          Used       Soft       Hard    Warn/Grace     
---------- -------------------------------------------------- 
root          1024000          0          0     00 [--------]
4000187             0          0    1048576     00 [--------]

Project quota on /var/backup (/dev/vdb1)
                               Blocks                     
Project ID       Used       Soft       Hard    Warn/Grace     
---------- -------------------------------------------------- 
4000187        512000          0    1048576     00 [--------]

Modifying a Project (Directory) Quota

To modify a project (directory) quota, you just set an new quota (limit) on the chosen project:

xfs_quota -x -c 'limit -p bhard=1048576k 4000187' /var/backup

Check your quota (limit)

xfs_quota -x -c 'quota -p 4000187' /var/backup

Removing a Project (Directory) Quota

Removing a quota from a project:

xfs_quota -x -c 'limit -p bhard=0 4000187' /var/backup

Chreck the results:

xfs_quota -x -c report /var/backup

User quota on /var/backup (/dev/vdb1)
                               Blocks                     
User ID          Used       Soft       Hard    Warn/Grace     
---------- -------------------------------------------------- 
root           512000          0          0     00 [--------]
4000187             0          0       1024     00 [--------]

As you can see, the line with the Project ID 4000187 has disappeared:

4000187        512000          0    1048576     00 [--------]

Don't forget to remove the project from /etc/projects and /etc/projid:

sed -i -e '/4000187/d' /etc/projects
sed -i -e '/4000187/d' /etc/projid

Some important notes concerning XFS

The quotacheck command has no effect on XFS filesystems. The first time quota accounting is turned on (at mount time), XFS does an automatic quotacheck internally; afterwards, the quota system will always be completely consistent until quotas are manually turned off.
There is no need for quota file(s) in the root of the XFS filesystem.

OpenSSH

Configure the OpenSSH daemon:

vi /etc/ssh/sshd_config

Set following options:

PubkeyAuthentication yes
PasswordAuthentication yes
UsePAM yes
Subsystem     sftp   internal-sftp

Make sure, that Subsystem sftp internal-sftp is the last line in the configuration file.

We want to reduce the numbers of chroot environments in one folder. As the ChrootDirectory configuration option only allows %h (home directory of the user) and %u (username of the user), we need to create the necessary matching rules in the form of:

Match User *000
  ChrootDirectory /var/backup/000/%u
Match
Match User *001
  ChrootDirectory /var/backup/001/%u
Match
...
Match User *999
  ChrootDirectory /var/backup/999/%u
Match

The creation of the matching rules is done by executing the following bash commands:

FILE=/etc/ssh/sshd_config;
 
for ((x=0; x<1000; x+=1)); \
do \
  printf "Match User *%03d\n" $x >> ${FILE}; \
  printf "  ChrootDirectory /var/backup/%03d/%%u\n" $x >> ${FILE}; \
  printf "Match\n" >> ${FILE}; \
done

Don't forget to restart the OpenSSH daemon:

/etc/init.d/sshd restart

sshd keys

If you migrate from a existing backup server, you might want to copy the ssh host keys to the new server. If you do so clients want see a difference between the two hosts as the fingerprint remains the same. Copy the following files from the existing host to the new:

/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_key
/etc/ssh/ssh_host_rsa_key
/etc/ssh/ssh_host_dsa_key.pub
/etc/ssh/ssh_host_ecdsa_key.pub
/etc/ssh/ssh_host_key.pub
/etc/ssh/ssh_host_rsa_key.pub

Set the correct permissions on the new host:

chmod 600 /etc/ssh/ssh_host_dsa_key /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_key /etc/ssh/ssh_host_rsa_key

And restart the ssh daemon. Caution: do not close your existing ssh session as long as you are not sure the ssh daemon restarted properly and you can login again.

Currently we just create very basic init scripts which start and stop the deamon:

/etc/init.d/prov-backup-rsnapshot

#!/sbin/runscript
# Copyright 1999-2013 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $

depend() {
    need net
    after slapd
}

start() {
    ebegin "Starting backup-rsnapshot provisioning daemon"
    start-stop-daemon --start \
        --background \
        --user ${USER:-root}:${GROUP:-root} \
        --make-pidfile \
        --pidfile "${PIDFILE}" \
        --exec /var/work/prov-backup-rsnapshot/Provisioning/bin/provisioning.pl \
        --interpreted \
        -- ${OPTIONS} \
            -c /var/work/prov-backup-rsnapshot/Provisioning/etc/Provisioning/Backup/Rsnapshot_test.conf \
            -g /var/work/prov-backup-rsnapshot/Provisioning/etc/Provisioning/Global.conf
    eend $?
}

stop() {
    ebegin "Stopping backup-rsnapshot provisioning daemon"
    start-stop-daemon --stop \
        --pidfile "${PIDFILE}"
    eend $?
}

/etc/conf.d/prov-backup-rsnapshot

USER="root"
GROUP="root"

PIDFILE="/run/prov-backup-rsnapshot.pid"
