Notes

Note: This is not specifically about backup. It's my one page for rsync, dump/restore, cpio, etc. differences and uses.

• dump/restore
  • you get one destination file that you can copy over to another system and restore from it (ala tar).
  • great for preserving hard links and creating an exact duplicate.
  • The source and destination filesystems have to match
    • i.e. both ext3fs or both btrfs, etc.
  • Important: Never use dump/restore on live filesystems, only on absolutely quiescent ones, preferably not even mounted read/write.
