So I am on Veeam community edition 11.01.1261 and decided to look into immutable backups. I created a Ubtunu 22.04.2 VM and followed the guide. I added the repo to Veeam. When I do a backup and check on the Linux system I am not seeing the immutable tag set, what am I missing? I’m looking in the data directory of the backupset. The backup is there, looks fine, it is not immutable. 

 lsattr
---------------------- ./0000.vblob
 

The Linux FS is XFS, and I set the checkbox to say it should be immutable for 7 days. 

What is your source? A VM or NAS data? I am asking because vblob looks like NAS Backup. And in v11 it is supported to Backup into hardened repo, but its not immutable. Starting v12 also NAS Backup can be immutable.

I humbly apologize, I must have missed that salient detail. Your right it was a SMB file share. I did a backup of a VM and the immutability flag is there. Thank you for responding. I greatly appreciate your expertise. You saved me a lot of time. 

Can I have an immutable repository running on Windows?

Hi, Sorry by Design its not possible (from Windows side) . I recommend linux hardened repo or object storage.

Hi @luhan.brito I never used it but exist Blocky for Windows

I only know that solution from theory. But it is NOT 1:1 comparible and not a true immutability. But it is addtional security and better than nothing. If Windows is mandatory maybe Look at this, in other cases i recommend linux Repos. 

Totally agree with you @MatzeB
