Initial snapshot need to be sent in full to the dest server: btrfs send /mnt/data/1st_snaphot | ssh root@ip "btrfs receive /mnt/backups" After that you send only the changes: btrfs send -p /mnt/data/1st_snaphot /mnt/data/2nd_snaphot | ssh root@ip "btrfs receive /mnt/backups" and so on.

There's some info here on how btrfs snapshots and send/receive work, difference is there it's sending locally, to send changes to another server you'd use for example: btrfs send -p /mnt/data/old_snaphot /mnt/data/new_snaphot | ssh root@ip "btrfs receive /mnt/backups" There's no GUI support, so you have to use the console or a script.

Yes, you can use btrfs send/receive over ssh, that's how I backup all my servers.

Note it's only not moving from array to pool, it still does from pool to array, even with a space in the name.

It's a bug, mover isn't working for shares with a space in the name, you should create a bug report. As a workaround you can rename the share, using for example an underscore.

Unfortunately you rebooted since the rebuild, did you save those diags by any chance? Still the errors suggest the rebuilt was corrupt.

Share doesn't yet exist on that disk, once it does space will be correct.

Please post the diagnostics: Tools -> Diagnostics

According to the mover log there's nothing to be moved, from what share are you trying to move data?

Enable mover logging, run the mover, post new diags.

If any rebuild was done after the controller dropping that disk will be corrupt, GUI would show errors on multiple disks, and you'd be notified if system notifications are enable.

It doesn't, you should have save them before rebooting.

sda is a flash drive, but since it-s spamming the log disconnect it if not in use, enable this and then post that log and the complete diagnostics after a crash.
