=== Project (Directory) Quotas ===
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 <code>/etc/fstab</code> entry from above.
* directory: The directory of the project (187/4000187), starting from the mountpoint of the xfs-filesystem (/var/backup).

Set Project:
xfs_quota -x -c 'project -s -p /var/backup/gugus3 3187/4000187 4000187' /var/backup
Check Project:
xfs_quota -x -c 'project -s limit -p /var/backup/gugus3 3bhard=1048576k 4000187' /var/backup
Set Limit
xfs_quota -x -c 'limit quota -p bhard=1048576k 34000187' /var/backup
Check the Quota:
* <code>-N </code>: suppress the initial header.
* <code>-p </code>: display project quota information.
