Ubuntu backup restore stuck at very large file

ch flag

I had to do a fresh install of Ubuntu on my computer and I'm now trying to restore my deja dup backups from my local NAS (via WiFi). This worked well until it hit a very large binary file (~ 100 GB) where it got stuck for hours (I kept it running over night but no progress).

I found a couple of older threads that mention that I just have to wait long enough. According to Nautilus, the last modification of this file was 1,5 hours ago and it is at 67 GB (of ~100 GB) now. So something happened over night. Is this the expected time to patch together the next chunk of data from the backup? Or is it actually stuck? System Monitor shows N/A for Disk read & Disk write on the deja-dup process. It also shows Disk write total of 3,6 GiB which is definitely way less than it has already written (what time frame is System Monitor showing here?).

What can I do in this situation?

  • is there any way to figure out if deja dup is still doing anything?
  • can I just cancel the Backup and start it again? Will it pick up where it got stuck?
  • can I delete files like this one from the backup before I restore it (it's a file I actually wouldn't have backed up in the first place but forgot to add it to the ignore list)?

How does deja dup deal with suspending the system? I guess my computer fell asleep for a short period of time yesterday (so way before the last write operation on that file). Could this have cause trouble?

Any help appreciated!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
