System Management Guide: Operating System and Devices
Backing Up User Files or File Systems
Three procedures can be used to back up files and file systems: the Web-based System Manager fast path wsm fs, 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 Version 4.3 System Management Concepts: Operating System and Devices.
Prerequisites
- If you are backing up file systems by i-node 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 displays. 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.
