error: data decryption failed - Can't List Snapshots

[ossie-git]

Hi,

I have a repository that suddenly won't allow me to list snapshots. It was working fine before today. This is what I see when I run a snapshots command:

$ rustic -P aws snapshots
[INFO] using config /home/o/.config/rustic/aws.toml
[INFO] repository local:/mnt/hard/O/Backups/Rustic/AWS: password is correct.
[INFO] using no cache
error: data decryption failed

Other commands such as find also don't work (I'm using the nightly builds):

$ rustic -P aws find --iglob "*.pdf"
[INFO] using config /home/o/.config/rustic/aws.toml
[INFO] repository local:/mnt/hard/O/Backups/Rustic/AWS: password is correct.
[INFO] using no cache

error: data decryption failed

At the same time, some commands such as backup do work:

$ rustic -P aws backup
[INFO] using config /home/o/.config/rustic/aws.toml
[INFO] repository local:/mnt/hard/O/Backups/Rustic/AWS: password is correct.

I'm currently using the following (as I want the find command):

$ rustic --version
rustic v0.7.0-45-gfc8e3c5-nightly

I also downloaded and tried it on the stable version and have the same problem:

$ ./rustic --version
rustic v0.7.0

My configuration is very simple (I have another repo with the exact same configuration options which is still working fine):

[repository]
repository = "/mnt/hard/O/Backups/Rustic/AWS"
password = "password"
no-cache = true # no cache needed for local repository

[forget]
keep-hourly = 24
keep-daily = 14
keep-weekly = 8
keep-monthly = 24
keep-yearly = 10

[backup]
#exclude-if-present = [".nobackup", "CACHEDIR.TAG"]
#glob-file = ["/root/rustic-local.glob"]
one-file-system = true

[[backup.sources]]
source = "/home/o/Downloads/AWS"
git-ignore = true

Any ideas? Thanks

Restic appears to be able to run snapshots on the repository:

$ restic -r /mnt/hard/O/Backups/Rustic/AWS/ snapshots
enter password for repository:

Seems like the snapshot file 7f008c6609065eb9a03134440168bebe280b4b0b6f56c6f6b0c6876f2e175915 is defect.

So yes, the error message should be improved such that you can see where data decryption failed. Also we could ignore defect snapshot files like restic does. These are IMO good UX improvements.

@ossie-git Can you please post the output of rustic check? There at least some useful information should be given, it not this is a UX bug, IMO.

@ossie-git Thanks. This is not how it should be 😉

Do you have any idea why the backup might have become corrupted. I'm just guessing but it might have been right as I was suspending my PC
