Not sure it will work as you would like, since VBK will be renamed upon compact operation and to get back to the name without a timestamp, you would need to start anew (see below).

According to this KB, the value works for new jobs or jobs for which you first perform the "Remove from backups" command. Also don't forget to restart the backup server after making this registry change.

Mmmmh so it should work one week, until the Saturday compact operation run.
Once compact will have run, the .vbk will be timestamped.
Then, will the .vbk name change everyday ? Or only the next Saturday, after the next compact operation ?
Thank you again Foggy !

VBK will be changed only upon compact operation, so it will remain the same (timstamped with the date of compact) during the week.

Foggy, thank you very much for your answer !
This behavior could help me a tittle though :)

Btw, did you manage to get in touch with dev team to propose them to support DisableVBKRename=1 even after compact operation ?

Thank you again !

We have this filed in our issue/feature tracking system since the beginning of this thread, but there's no particular ETA for this at the moment.

Anyway, thank you very much for your confirmation, and let's then stay tuned !

Foggy, I confirm the behaviour, VBK name changes only upon compact operation, otherwise it remains the same (timestamped with the date of compact).

I would really be glad if you could support DisableVBKRename=1 even after compact operation, in upcoming update 3 for Veeam Backup & Replication 9.5.
That would really be good news !
If we think about it, the fix should be quite tiny to write (compared to other ones), don't you think so ?

Thank you very much again to you and dev team for your support !

I think rsync will have a tough time finding out the bytes unless compression is disabled (which you probably don't want during your WAN transfer).

Currently testing in a home lab but had a similar case where I wanted to get my Veeam backups onto offline cloud storage and noticed that the file had a different name. My thoughts were that this shouldn't matter since the program that I was using (hashbackup) supports deduplication.

The trick to get it to work well (high deduplication with full files regardless of name/timestamp) was to disable compression entirely and keep on inline deduplication optimized for a lan target.

So flow is basically backup takes place with Veeam (no compression). Script runs to trigger hashbackup which compresses and deduplicates the files before putting them on the cloud. A Veeam backup directory of about 46GB would go down to around 6.5GB of files. If enabling any compression it would totally throw off hashbackups deduplication. I'm making some assumptions here but I don't see how rsync would work any better.
