Use this procedure to perform an offline backup of any changes since a previous backup.
To perform incremental backups, you must perform a full backup as a reference to create the first incremental backup of a sequence. Keep the most recent full backup and a complete sequence of incremental backups to restore from.

Warning
|
Request other users of {ProjectServer} or {SmartProxyServer} to save any changes and warn them that {Project} services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup. |
-
Ensure that your backup location has sufficient available disk space to store the backup. For more information, see [Estimating_the_Size_of_a_Backup_{context}].
-
To perform a full offline backup, enter the following command:
# {foreman-maintain} backup offline /var/backup_directory -
To create a directory within your backup directory to store the first incremental back up, enter the
{foreman-maintain} backupcommand with the--incrementaloption:# {foreman-maintain} backup offline --incremental /var/backup_directory/full_backup /var/backup_directory -
To create the second incremental backup, enter the
{foreman-maintain} backupcommand with the--incrementaloption and include the path to the first incremental backup to indicate the starting point for the next increment. This creates a directory for the second incremental backup in your backup directory:# {foreman-maintain} backup offline --incremental /var/backup_directory/first_incremental_backup /var/backup_directory -
Optional: If you want to point to a different version of the backup, and make a series of increments with that version of the backup as the starting point, you can do this at any time. For example, if you want to make a new incremental backup from the full backup rather than the first or second incremental backup, point to the full backup directory:
# {foreman-maintain} backup offline --incremental /var/backup_directory/full_backup /var/backup_directory
