Consolidation ensures that backups that have been created are grouped together. The backup chains are kept short, which reduces the recovery time. In addition, the consolidation saves storage space.
Backups are made every hour, Monday through Friday, from 8 a.m. to 6 p.m. That's 10 incremental backups per day, 50 incremental backups per week and 200 per month.
A consolidation is recommended for example on Saturday 10 p.m. when there is no high activity on the Servers. If, for example, the consolidation takes place within 4 p.m. of the week, this can take a lot longer because the backups and other activities run in parallel. In addition, a backup may not be possible if the file is blocked by the consolidation during the scan.
This example ensures that the backup chain has a maximum of 150 files as a result of the consolidation. A backup chain that is too long requires more memory and increases the recovery time.
Leave latest XX incremental file(s)
Re-consolidate already consolidated incremental image files
If the backup is also replicated to other locations, another ImageCenter can be used, which consolidates the received data again, for example in the data center.
Keep last: 30 incremental File(s)
Re-consolidate already consolidated incremental image files + keep: 31 consolidated incr. image file(s)
With these settings, 30 incremental files, the hourly backups can be accessed 3 days retrospectively. With the 31 reconsolidated, a retrospective period of one month is given, as these have already been combined. The memory in the data center is only used minimally and the backups are stored redundantly. The previously consolidated data is stored on the customer's side and enables detailed access on an hourly basis.
Keep original image files
When backup files are consolidated, the original incremental files are automatically deleted. If it is necessary to use the originals for reasons, in order to access them every hour, as in the above example, this option can be activated. This copies the originals to a subfolder and either stores them until the next consolidation or for a certain period in days.
