Just running BackupMenu 1.10 from repo. Are there any changes to backup functionality? Seems backup is way slower than before. I'd estimate a factor of three or four.
After booting into backupmenu I first did a fsck on all partitions and then directly headed to creating a backup of both partitions to MyDocs, just as usual. But now it's already running six minutes for OptFS and only has about half the size backed up. Formerly it used to be finished after about four minutes.

EDIT:
Didn't look at the screen when it finished but I guess it took around 11 minutes to finish the backup.

And a big thank you for adding the power off option!
