Hello, so today I needed to import a Backup. from an SD card but it failed. Later on I found out that the archive is corrupted and repairing it didnt work.
So is there a way (at least manually) how to get atleast some data from the corrupted Backup?
(Original data are gone, so its out of question. Update gone wrong thank to BTRFS)

Sorry for the late answer, question notification was missed from my notifications inbox. You can try to extract data from the tar file manually. To do it you should first create /home/nemo/.vault directory and try to extract the file into it (like mkdir /home/nemo/.vault && tar xvf <path-to-your-backup-tar> -C /home/nemo/.vault. You should be cautious: if tar archive is considered as corrupted by backup application maybe metadata is corrupted.
Just wondering; why should users manually create /home/nemo/.vault dir? Shouldn't it always be in the phone, unless user has manually removed it? IMO even using the Jolla Utilities "Clear backup storage" tool does not erease the .vault from nemo-user home but just all the backups in there, right?

mkdir -p /home/nemo/.vault && tar xvf Backup.tar -C /home/nemo/.vault
(note the -p option in mkdir)

How is your backup.tar corrupted? What does it mean that ypu tried to "import" it? Do you mean you tried to restore app data from the backup? Did you use the GUI to make it and restore it? What data was there in the backup, how big is it? Does the Backup.tar contain several baclup's,made in the Settings > Backup or is there only one? What error messages when you tried to restore from that, in GUI or in CLI. How did you try to tepair it, what commands did you use? Just asking these cause the way you described the problem, really makes it quite impossible for others to diagnose, confirm or fix this issue. It'd really help if you could detail the issue you are experiencing by givibg us some more info in the Q description itself. Thanks!
