[Duplicity-talk] --full-if-older-than 26W oddity

[Andrew Kohlsmith (lists)]

Good morning,

I've been using duplicity for about 6 months, and I upgraded (reinstalled) one 
of the servers I back up, It's been 2 months since I ran a backup last.

My typical backup line looks like this:

duplicity --full-if-older-than 26W --archive-dir 
${ARCHIVEDIR}/root --encrypt-key ${MIXDOWN_KEY} --encrypt-key 
${ANDREW_KEY} --include /etc --include /usr/local/scripts --exclude '**' / 
file:///mnt/duplicity/media.mixdown.ca/root

When I ran the backup last night, it said that the last incremental was done 
too long ago (Oct 31 2008) and that it was going to do a full backup.

My question is why... The date on the server is correct, the timestamp on the 
incremental backups is fine...  Am I specifying "26 weeks" incorrectly?

Regards,
Andrew
