Is it possible to restore a duplicity backup from a certain time in the past?

For example, if I'm making daily incremental backups, is there a way to restore a backup from three days ago?

The -t argument will tell duplicity from what time to restore.

duplicity -t 3D --file-to-restore FILENAME scp://uid@other.host/some_dir /home/me/restored_file

Will restore FILENAME from 3 days ago. If you don't do daily backups and use a non-existing day the restore command will pick the date closest to your date.

  • Does this mean though, restore the first backup found that was before 3 days, or the first backup after 3 days ago?

I don't know duplicity, but the general restore process is to go back to the first FULL backup PRIOR to the date you want to restore to. Restore that FULL backup, then restore ALL the incremental backups since that FULL backup, in date order, until you get to the date you want.

    Thanks for the info, very interesting comment. I'm more of a programmer than a sysadmin, so I'm no expert in this field; can anybody else recommend this as a best practice? If so, please mod Jeff up! Thanks... Mar 3 '11 at 17:46

    that used to be the case if you are using tape based backup. if disk based (rsnapshot/rsync etc) you dont have to anymore

    In fact, duplicity will do exactly that for you.
