IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive ...

|||||incrementalSpecifies that you want to back up only new and changed files after the mostrecent image backup (full or incremental). If an image backup has not yet beenmade, then the first backup will be a full image backup, regardless of themode option.fullDeleted files are not marked inactive on the server.Specifies that you want to perform a full backup of NAS, WAS, or groupobjects. This is the default for WAS and group backups.differentialThis is the default for NAS objects. Specifies that you want to perform a NAS,WAS, or group backup of files that changed since the last full backup. If thereis no copy of a full image stored on the Tivoli Storage Manager server, a fullbackup occurs. If a full image exists, whether it is restorable, or expired andbeing maintained because of dependent differential images, specifying MODE=differential sends a differential image backup. If a full image is sent during adifferential backup, it is reflected as a full image using the query nasbackupserver command.A full image can be eligible for expiration based on versioning or retention(verexists retextra), but still be maintained on the Tivoli Storage Managerserver to allow for restoring dependent differential images. A full image that iseligible for expiration cannot be selected for restore, so it is not displayed usingthe query nasbackup server command. The differential image backups thatdepend on an ″expired″ full image can be restored.ExamplesTask Perform the NAS image backup of the entire file system.Command: dsmc backup nas -mode=full -nasnodename=nas1 /vol/vol0/vol/vol1Task Back up the /home/test file space using an image incremental backup thatbacks up only new and changed files after the last full image backup.Command: dsmc backup image /home/test -mode=incrementalTask Perform a full backup of all the files in filelist /home/dir1/filelist1 to thevirtual file space name /virtfs containing the group leader /home/group1file.Command:backup group -filelist=/home/dir1/filelist1 -groupname=group1-virtualfsname=/virtfs -mode=full292 IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
