The GFS tape job creates yearly archive for source machines by the GFS (Grandfather-Father-Son) scheme. The GFS archive includes one yearly backup and several quarterly, monthly, weekly and daily backups.
You can create GFS backups for VMs and Veeam agent computers (physical machines) on tape.
The GFS tape job does not process source machines. The job uses backups created by machine-to-disk jobs.
GFS Media Sets
To distinguish between the backup cycles, the GFS media pool has 5 pre-defined media sets: yearly, quarterly, monthly, weekly and daily.
Restore Point Type
Full backup or synthesized virtual full backup
As on disk (for details, see How GFS Backup to Tape Works)
Individual Media Sets Configuration
You can configure each media set individually. You can set retention period, appending data to tape or other settings for each media set separately.
For example, the weekly backups must be stored for 4 weeks, data is appended, tapes may be overwritten. The yearly backups must be never overwritten, each backup on an individual tape (or set of tapes), tapes must be moved to vault.
Manual Active Full
You can manually create a restore point for any media set at any time with the Active full option. Veeam Backup & Replication will copy or synthesize the most recent full backup possible for the selected period. The manual active full is not available for the Daily media set.
If the schedule for backup periods overlap, only the backup for the eldest media set will be archived. The media sets have the following priority: Yearly, Quarterly, Monthly, Weekly, Daily. For example, if "the first Sunday of January" is the date for the monthly, the quarterly and the yearly backup, the GFS job will create only the yearly backup; the monthly and the quarterly backups will be skipped.
