How can i limit the number of versions for samba modul shadow_copy2

Hello all,

we use here UCS version 5.0-6 and sambashares on BTRFS. Now we enabled shadowcopy on the server for us Windows Clients. This is working, but i did not find how i can limit the number of versions of the snapshots.

Does anyone know how this will be configured?

best regards

What do you to expect to happen when the limit is reached? No additional can be created? I guess probably not, maybe you want the new copy to happen and then a cleanup job should remove the oldest? In that case a cron job would be one way.

The problem is there is no limit, at least I can’t find a way to configure it in Samba. The Samba documentation doesn’t mention it either. The snapshots already went into the millions and had a virtual size of over 1.5PB. Deleting them was a pain.

mybe that help’s - i don’t use shadow copys at all - so not tested that


It’s more complex than you might think…
I have now found this file:


Does anyone know this? Has a UCS header. But I can’t find or reproduce it on any other system.
