However, this only backs up files with a changed date,not files with changed permissions.Related reference“Backup Image” on page 448The backup image command creates an image backup of one or more volumes onyour system. These volumes can be formatted FAT, FAT32, NTFS, or unformattedRAW volumes. If a volume is NTFS-formatted, only those blocks used by the filesystem will be backed up. If you set the imagegapsize option to 0, all blocks,including unused blocks at the end of the volume, will be backed up.“Mode” on page 350Use the mode option with the backup group, backup image, backup nas, andbackup was commands (if applicable) to specify whether you want to perform afull or differential group backup containing a list of files from one or more filespaces.“Restore Image” on page 513The restore image command restores a file system or raw volume image that wasbacked up using the backup image command.Performing snapshot-based file backup and archive andsnapshot-based image backupFor Tivoli Storage Manager clients running on AIX 5.3 or later JFS2 file systems asroot user, snapshot-based image backup will be created using snapshots by default.Optionally, you can enable snapshot-based file level backup and archive operationsby specifying the snapshotproviderfs option. If for some reason a snapshot cannotbe taken, Tivoli Storage Manager will attempt to perform a static image backup orregular file backup.Chapter 4. Backing up your data 145
