Deduplication Question

[tsauter]

Hi,

I have one question regarding the deduplication feature (version 7). Is the deduplication calculated calculated through all backups in a backup repsitory or just only within the members of a job?
Does this mean, if I delete a complete job from a repository I will loose all other backups too because these jobs might need blocks from other backups?

Thanks for clarifiy this for me.

Hello,

Does this mean, if I delete a complete job from a repository I will loose all other backups too because these jobs might need blocks from other backups?

No, you will not lose anything. Dedupe is per job, not per repository.

Thanks!

Do you known the section of the manual where this is explained or sepcified?
Two of our software vendors claim that the dedup is always over the complete storage.

If the dedup is only per backup job, this means, if I write the contents of the CIFS share to a tape drive (not with veeam) I only need to restore the content of the job directory?

Thank you!

In addition to this, there are some details in our online help center > http://helpcenter.veeam.com/backup/70/v ... uplication

Yes, that's correct. You will need to restore VBK + VRB/VIB files to restore VM data.

Hope this helps!
