DEJA DUP: backup fails

[Samambaia]

Hi,

Here is my story: I uses DEJA DUP for backup, with a 4 years' old TOSHIBA mechanical hard drive that gave me an error like:

Code: Select all

Abandonner après 5 tentatives. Error: Error opening file “/media/nicolas/SSD/sauvegarde20210903/duplicity-full.20210923T092406Z.vol1.difftar.gpg”: Input/output error

I read it could be due to a hardware problem (disc would be faulty), and brought a brand new 2T SDD hard drive. But, after 1st back up, the problem reappears. I then exclude a hard drive problem on Toshiba.

I format the SDD again, didn't check for encryption, made it as simple as possible, and now it says:

Code: Select all

Impossible de lire /home/nicolas/.cache/deja-dup/tmp/duplicity-0pirszde-tempdir/mktemp-176c1n1z-1 : (<class 'gzip.BadGzipFile'>, BadGzipFile("Not a gzipped file (b'\\xff\\xff')"), <traceback object at 0x7fa1873dc640>)

According to you, what could be the solution?

Thanks,

Sounds like you're trying to restore your stuff from either (a) a bad drive or (b) a drive that doesn't have any such files to restore.

In other words, the problem exists between the keyboard and the chair.

Uhm... as a matter of fact, the error appears during backup, when backup make a self test of restoration (1st backup for the brand new SDD).

The first message appears, actually, during the monthly test of self test of restoration (on the mechanical TOSHIBA hard drive).

As the new SDD is new, I would eliminate a hard drive problem.

Any solution?
