Backup and Recovery How-To

From The Linux Documentation Project

2.1. Limitations

This HOWTO is restricted to making a minimal backup such that, having then restored that backup to new hardware ("bare metal" ), you can then use your regular backups to restore a completely working system. This HOWTO does not deal with your regular backups at all.

Even within that narrow brief, this HOWTO is not exhaustive. You still have some research, script editing, and testing to do.

The scripts here restore the partition data exactly as found on the source hard drive. This is nice if you are restoring on an identical computer or at least an identical hard drive, but that is often not the case. For now, there are two remedies (which will make more sense after you've read the rest of the HOWTO):

  • Edit the partition table input file. I've done that a few times. You can also do this to add new partitions or delete existing ones (but edit the scripts that use the partition table input file as well).

  • Hand build a new partition table and go from there. That is one reason why rebuilding script does not call the hard drive rebuilding script. Use the rebuilding script .

The scripts shown here only handle ext2fs, FAT12, FAT16 and FAT32. Until some eager volunteer supplies code for doing so in these scripts, you will need other tools for backing up and restoring file systems we haven't covered. Partition Image looks like a useful candidate here.
