Status and check-tab missing

[Anders Wallenquist]

I thing its important to check the integrity of the backup now and then, there have to be a status and check-tab in the control program for deja dup.

[Michael Terry (mterry)]

Thanks for the report! In development versions (23.x and soon 24.0), we do. After every backup, we make a small check to confirm we can restore a test file. And every two months, we make a more intensive check.

how to check the installed version of deja-dup ?
(I guess synpatic and software-center are one way; any command-line or other GUI ways?)

"how to check the installed version of deja-dup ?" - CLI solution:

deja-dup --version

[mkoniecz (matkoniecz)]

Is there any method to trigger this check? Is there checking whatever file content/checksum matches?

I want to be a able to create backup, verify it, wipe system and restore it.

[Naël (nathanael-naeri)]

I suppose you can run 'duplicity verify' to trigger the check you want, possibly with the --compare-data option to force comparison of the data itself (rather than of the filesize and timestamp as I suppose the default is).

Grep 'duplicity verify' in the output of a verbose manual backup 'DEJA_DUP_DEBUG=1 deja-dup --backup' to see the check that Déjà Dup runs after the backup, and that Michael mentioned in comment #1.

Beware that he advised against relying on a unique Déjà Dup/duplicity backup when upgrading or reinstalling systems, which seems to be your use case: https://mterry.name/log/2011/09/19/backups-and-distro-upgrading
