Is it just me or did Time Machine backups stop working with TrueNAS-Fangtooth-RC? Things are working fine before the update but now I get The selected network backup disk does not support the required capabilities.
What? I even created a new dataset and share - get the same error.
If you have configured some SMB shares with the mutliprotocol NFS preset, then time machine shares may be affected because enabling kernel oplock breaks requires disabling SMB2/3 lease support (which is required by Time Machine).
Yes … I had one unrelated share configured as multi protocol. Reconfigured and Time Machine is working again. Thank You.
@awalkerix Does that mean that if you need to use time machine you can’t have any shares using multiprotocol preset (i.e. NFS + SMB)? Or is this just specific for the TM share?
In my setup the TM share is just SMB but I have other shares that are multiprotocol.

I have similar questions.
For example I use a multi protocol share for isos… and I have a multi user Time Machine…
I guess I could switch to SMB for the isos.
The above language, with my added emphasis, suggests that having any multi-protocol share in the system is incompatible with Time Machine. Hopefully, @awalkerix can come back and provide an authoritative answer.
Is there any update to this? I just upgraded to Fangtooth and my Time Machine share no longer works for backups. I don’t want to disable NFS on my other non-Time Machine shares as most of my other machines are using them with NFS.
No update: You cannot have TimeMachine if there is any multi-protocol share.
