Adding Windows Security Group

[fret]

Hello,

Does anyone know since I am new to working with Veeam Backup&Replication 9.5 update 9.4 Community edition, I plan to add a security group to a 6Tb disk that is backed up, whether writing new rights will be understood as a new change for incremental backup?

Hi Sasa,

thanks for joining the community.
9.5 update 4 is a 2,5year old product. Please download v11 from our download page and use this one.

Is your question, what happens when you change the security ACLs of files within a VM?
Veeam backs up on block level, this means we backup all the bytes that are really changing on the storage system, not what we see on the filesystem.
If you change ACLs of a file, there are very small changes on the disk level to update the metadata within the file system table. But it is not the 6TB of data.

If you would overwrite the full file (write it newly) then we would need to backup all the things that are written to it.

If you use another backup methods then VM backup please let me know what you use.

Yes, my question was: what happens when you change the security ACLs of files within a VM? So, I dont have to worry about changing ACLs on all files and folders on 6TB disk with possible enormous incremental? I'm planing to switch to v11 soon!

Correct, as long as the change do not touch the data itself it looks like a very small change on disk level.
