Multiples questions regarding VEEAM

[Baptiste]

Hello everybody,

i have some question regarding VEEAM and i cannot find the answer online :

1) When you are doing a reverse incremental or a forever forward incremental and check the "remove deleted VMs data from backup after 14 days", when does the .vbk is compacted ? I belived it's never compacted in reverse but how about forever forward ? Does an active full backup is mandatory ?

2) When you are changing dedup in a working job, when is it apply ? Does it affect previous backup chain ? ( it changed since v8 )

3 ) When you are changing compression level in a working job, when is it apply ? Does it affect previous backup chain ? ( it changed since v8 )

Thanks for your help

Nobody knows ?

Most of those questions have been covered already on these forums. So, kindly, check the previous answers, and ask for additional clarification, if it's still required. Thanks.

I believe the behavior is the same: after the specified amount of days, blocks belonging to the deleted VMs in VBK are marked as free and then can be re-used by the new data. To reclaim the space, you need to perform an active full.
