[Duplicity-talk] Restore files older than the last full backup

[Rodrigo Campos]

Hi,

I'm using duplicity 0.6.24 on the server to backup to Amazon S3. To do the
backup, I'm using backupninja that runs duplicity like this:

        duplicity cleanup --force --s3-use-new-style --volsize 100
        --no-print-statistics --ssh-options '' --encrypt-key <somekey>
        --full-if-older-than 30D --extra-clean --archive-dir
        /var/cache/backupninja/duplicity s3+http://<some aws bucket>

        duplicity remove-older-than 60D --force --s3-use-new-style --volsize 100
        --no-print-statistics --ssh-options '' --encrypt-key <some key>
        --full-if-older-than 30D --extra-clean --archive-dir
        /var/cache/backupninja/duplicity s3+http://<some aws bucket>

        duplicity  --s3-use-new-style --volsize 100 --no-print-statistics
        --ssh-options '' --encrypt-key <some key> --full-if-older-than 30D
        --extra-clean --archive-dir /var/cache/backupninja/duplicity  --exclude
        '/home/*/.gnupg' --exclude '/root/.gnupg' --exclude
        '/var/cache/backupninja/duplicity' 
        --include '/var/backups/mysql/sqldump/' --exclude '**' /
        s3+http://<aws bucket>

And all works fine, I can list the files and everything using duplicity. It's
great. The thing is when I want to recover a file older than the last full
backup (recover from dates after the last full backup works fine). Then, it
fails with:

        duplicity restore --file-to-restore <file> --time 2015-10-12 
's3+http://<aws bucket>' /tmp/restore
        Local and Remote metadata are synchronized, no sync needed.
        Last full backup date: Tue Nov 10 01:20:30 2015
        <file> not found in archive, no files restored.

The thing is that the file is in the archive for backups previous than the last
full backup. I thought that the "remove-older-than 60D ..." makes duplicity
keep the last 2 full backups (as I'm doing "--full-if-older-than 30D") and I'd
be able to restore those files.

It seems all the duplicity files are there for previous full backups in the
amazon S3 bucket, but I found the last full backup has a file named:
        duplicity-full-signatures.20151110T042030Z.sigtar.gpg

and previous backups don't. If not for that file, all other files from previous
backups seem to be there.

Oh, and I'm running the restore on duplicity 0.7.05.

Is there something wrong on what I'm doing to backup or try to restore the
files? Does anyone have any idea on what to try?



Thanks a lot,
Rodrigo
