TimeMachine fails to backup to SMB with not enough space error

[davydden]

Dear all,

It has been a while I am trying to resolve this issue. At some point my TM backup stoped working, I recall TM suggested to re-create a backup from scratch.
Now every time I try to create a backup eventually I see:

"The backup disk needs 129,05 GB for the backup but only 1,04 GB are available. Select a larger backup disk or make the backup smaller by excluding files."

As for the setup:
- FreeNAS 11.3 Stable (latest)
- Data set has 1.46 TiB quota, read/write/execute permissions for User/Group
- SMB share has "Time Machine" option checked.
- I connect via a user which is a part of the corresponding group.

When I connect from a Finder, I definitely can delete the time machine backup bundle and/or create files, so write access is there.
I looked through multiple posts here and on Stackoverflow, but could not find a solution to my problem.

I would appreciate any help to dig to the bottom of the issue and hopefully get it resolved, as this is really annoying.

Sincerely,
Denis.

The problem was resolved by re-creating a pool and re-creating the share, following https://www.ixsystems.com/documenta...reating-authenticated-and-time-machine-shares

I did not have to setup fruit part, TM picked up the pool size, perhaps fruit is needed only when a pool does not a size limit set.
