I have a problem with Deja-Dup automatic backup. I want to backup several partitions daily after attaching external usb drive. However I encountered silly problem - Deja-Dup (or should I write duplicity) when launched automatically cannot write to a selected directory on this external disk. If I understand this correctly the problem is classic "no sudo".
So there goes my question - what should I do to make it happen. In my task manager I see a process called 'deja-dup-monitor' running. My understanding is that this process starts a deja-dup program when external disk is mounted (maybe it does this only because it wants to make initial backup and has to show a dialog asking whether I'd like to password it). It is then that actual backup is launched in form of duplicity process - and it seems this process doesn't have su rights.
That's my take on it, but I may be wrong.
I'd like to hear any suggestions and btw if you happen to know I have also questions regarding backing up itself:
- Does this program make daily backups at fixed hour or will it make backup after mounting external disk (can I check it for example in cron or something)?
- Will I be warned if it wants to make a backup and disk is not mounted?
- Will I be informed in any way about back up process (will it go silent, always popup deja-dup window or maybe show some icon in the taskbar - desired)?
- Is it possible to view progress of backup (I know only initial backup is long, but still)?
And finally your personal opinion - should I leave this idea and maybe make cron notifiy me to make the backup manually? (persistent notifications in gnome 3 seem apropriate for the task, hihi)
