How do I backup my stuff?

Snapshots and Hardlinks

Snapshots
  • A snapshot of /home/simonh shows what my home-dir looked like yesterday (or last week, or last month. . .  )
  • Makes "undelete" (file recovery) trivially-easy.
Hardlinks
  • Snapshots implemented by hard links (contrast soft/sym links).
  • cp -l
  • Variant on previous script:
        rsync -a --hard-links --delete --backup \
                 --backup-dir=$SNAPSDIR $SRCACCNT $RSYNCDIR/
