My backups appear successful, but they take hours even for 8 GB. I attributed this to poor WiFi and upload speeds because I’m traveling, but now I’m not so sure.
I’ve tried a restore a few times and I see a lot of errors due to “unexpected pack size.” I have yet to see a restore succeed.
It’s hard to say much about it without more information. Can you please tell us what internet connection you have, and also paste here the complete command and output from it for when you back up using restic? Please also include the restic version you have. Also please make sure that the problem persists when you use the very latest 0.10.0 release of restic.
