Increment Backup

Increment backup is one of three backup types (methods) supported by Genie Games Backup, it includes all files that have changed since the last backup run (regardless of whether it is normal or incremental), using, by default, the files' last modified date and time stamp. Deleted files will not be removed from the backup set. During restore, the first full backup, and all subsequent increments must be available in order restore data.

To set Genie Games Backup to perform an increment backup:

From the left navigation menu in the backup wizard select Settings
From Backup Type select Increment

Rollback

Enabling rollback during increment backup will cause Genie Games Backup to keep old versions of modified files backed up in previous runs (revisioning), this way the user can still restore (rollback to) any backed up version of a certain file to protect against losing data by mistake.

With rollback enabled, each backup run will create a new file/folder on the storage media containing new and changed files. A number appended at the end of the filename will be incremented by one, to denote a new backup run, starting with zero (0). For example:

Backup Job.gbp ... Normal Backup

Backup Job.0.gbp ... First increment/differential backup run

Backup Job.1.gbp ... Second increment/differential backup run

Backup Job.2.gbp ... Third increment/differential backup run

Note

Disabling rollback in a backup job will also disable cataloging.

Disabling Rollback

Disabling rollback means that Genie Games Backup will append new files to the main backup file/folder. Changed files will overwrite older versions stored within the backup set.

Notes about disabling rollback:

When backup using compression is selected, if the data after compression exceeds 2GB in size, rollback will be forced.
No catalog entries will be recorded when rollback is disabled.
Backup without rollback is not supported when media is not rewritable, or if the user does not have delete permission on the storage location.

Purging with Increment Backup

When using incremental backup, every file created by any backup job is crucial for the entire backup set, removing one increment will render increments created afterwards corrupt. However, when a new normal backup run is performed, it starts a new standalone backup archive. When purging is used with incremental backup, Genie Games Backup treats each normal backup and subsequent increments as one backup set; each time the user switches to normal backup, the previous backup set can be deleted safely.
