[drbrezner]

hi!

i'm using duply for years now for doing backups into a gmail account. the old one became full and i switched to a new one and now i get at the end of a full backup run this cryptic error:

anyone with the same problem? is it a gmail problem or a duply/duplicity thing or even some python related stuff?

My german doesn't work, so I've got what google translate told me.

According to that, it might seem that your duplicity didn't find signatures of a previous backup. Did you attempt a full backup first?

This happened from the very beginning -- i made a new fresh gmail account, changed the login-information in duply's config file, then i started a full backup. This transfers all the data and in the end it fails with the posted message. I also tried deleting everything in the gmail-account agin and all duply cache-files i could find.

Never used duply to back up things against gmail, but I've run into some issues with the recent security measures from google. Try to send an email using the account's credentials and try to figure out if google is blocking you in some manner. If you're blocked, then try to get access from that box to the email functionality and after that try to back up things again.

I set up thunderbird for that mail account using imap access -- sending and receiving email works without any problem. It's really strange. Some other duply profiles work with the old mail account without any problem. Only the second account keeps making problems. duply transfers data and the files are stored in the gmail account but in the end, duply still crashes.

I don't quite understand why it is working now but i changed duply conf-file for that backup profile from VOLSIZE=10 to VOLSIZE=5 and now it's working perfectly.

Really strange, since all my other duply backups work perfectly fine with VOLSIZE=10 on gmail accounts.
