If the deduplication settings are changed for an existing job, when will the new settings be applied?
If the deduplication settings are changed for an existing job, when will the new settings be applied?
The new deduplication settings will be applied only when a new active full backup is created. This is because deduplication is dependent on the block size used during the backup process, and a new active full backup is required to establish a new baseline for this deduplication process. Consequently, previously created backup files in the backup chain will not be affected by the new settings.
I believe this is A. See https://helpcenter.veeam.com/archive/backup/95/vsphere/compression_deduplication.html
The question is about deduplication not encryption or data compression. https://helpcenter.veeam.com/docs/backup/vsphere/compression_deduplication.html?ver=110 You can change data deduplication settings for existing jobs. After you change the settings, you will not need to create new full backups to enable or disable the deduplication. Veeam Backup & Replication will automatically apply the change to the newly created backup files after you save the settings. Previously created backup files will not be affected.
i think A because : * new compression settings are aplied at the next run of this job, * new deduplication settings are apllied only after a new active full backup is created
B is the correct - see the note & link below under Changing Data Deduplication Settings: https://helpcenter.veeam.com/archive/backup/95/vsphere/compression_deduplication.html You can change data deduplication settings for existing backup jobs. New settings will not have any effect on previously created backup files in the backup chain. They will be applied to new backup files created after the settings were changed.
Data deduplication settings can be changed on the fly. You do not need to create new full backups to enable/disable the settings. Veeam Backup & Replication will automatically apply the change to the newly created backup files after you save the settings. Previously created backup files will not be affected.
A, https://helpcenter.veeam.com/archive/backup/95/vsphere/compression_deduplication.html
To apply new deduplication settings in backup jobs, you must create an active full backup after you change deduplication settings. Veeam Backup & Replication will use the new block size for the active full backup and subsequent backup files in the backup chain. A is correct
It's A. Dedupe is applied at next full backup and compression is applied at next run. Dedup depends upon the chain of previous full backup.
