Re: [Duplicity-talk] Strange exception during a restore with 1.2.1 from AWS

[Kenneth Loafman]

That specific error says that volume 272 difftar of the backupset is missing.  Not a good error message by any means.

You can check on S3 to see if somehow it did not get downloaded, but my guess is that it is indeed missing.

Did you have any restarts during the backup?  Did you verify the backup?

Dear all,

I am testing the viability of my backups by restoring to a blank Linux
computer loaded up with the decryption keys and the same patched
duplicity 1.2.1 that I used for the backup (just a patch for the doubled
--encrypt option and one for lowering the threshold for displaying
actual progress numbers instead of "Stalled").

However when restoring a large partition, instead of restoring, it fails
with the error messages below, the message doesn't say what the error is
or what it was trying to do, just an error number and traceback of the
stack with no specific context:
