CHAPTER 4 Work Required After Operating System Installation
(3) Back up to media
Back up to backup media for each partition of the disk.
The dump command is used for backup, but it supports the ext2 and ext3 file systems
only. Use the tar command to back up /boot/efi of a different file system.
Note: Be careful when different tape units are used for backup and restoration
because the default block sizes of the tape units may be different. Execute
backup and restoration based on the same block size. Restoration fails if the
block size used for restoration differs from that used for backup.
