I'm not regular user of BackUpMenu. I just installed version 1.2.0-1. I started to create backup of root and opt. And got confused how much I need spare space.

Now I'm reading /usr/share/backupmenu/BackupMenu.item:778 And I'm still not understanding help text about "Make sure you have 2GB+ of free space on..." I mean, is this hint for both selections or only for the latter?

It should not use hardcoded 2GB, but check how much there are data to backup. Compressed size can be only estimate. (Yes, I have bigger opt than 2GB)


It got rootfs done and when my disk run out of space with optfs, it gave "Error 2" + "OptFS Backup complete" + "All operations completed successfully."

And indeed when unpacking I got "Unexpected EOF in archive".
