System Management Guide: Operating System and Devices

Backing Up User Files or File Systems

Two procedures can be used to back up files and file systems: the SMIT fast paths smit backfile or smit backfilesys, and the backup command.

For additional information about backing up user files or file systems, see Backing Up User Files or File Systems in the AIX 5L Version 5.1 System Management Concepts: Operating System and Devices.

Prerequisites

If you are backing up inode file systems that may be in use, unmount them first to prevent inconsistencies.
Attention: If you attempt to back up a mounted file system, a warning message is displayed. The backup command continues, but inconsistencies in the file system may occur. This warning does not apply to the root (/) file system.
To prevent errors, make sure the backup device has been cleaned recently.

Backing Up User Files or File Systems Tasks
Task	SMIT Fast Path	Command or File
Back Up User Files	smit backfile	Log in to your user account. Backup: find . -print \| backup -ivf /dev/rmt0
Back Up User File Systems	smit backfilesys	Unmount files systems that you plan to back up. For example: umount all or umount /home /filesys1 Verify the file systems. For example: fsck /home /filesys1 Back up by i-node. For example: backup -5 -uf/dev/rmt0 /home/libr Restore the files using the following command:¹ restore -t

Note:

If this command generates an error message, you must repeat the entire backup.
