Method 1: Using image backup with file system incrementalUse this method to perform image backups with file system incremental.1. Perform a full incremental backup of the file system. This establishes a baselinefor future incremental backups.2. Perform an image backup of the same file system to make image restorespossible.3. Perform incremental backups of the file system periodically to ensure that theserver records additions and deletions accurately.4. Perform an image backup periodically to ensure faster restore.5. Restore your data by performing an incremental restore. Ensure that you selectthe Image plus incremental directories and files and Delete inactive filesfrom local options in the Restore Options window before beginning the restore.During the restore, the client does the following:v Restores the most recent image on the server.vvDeletes all of the files restored in the previous step which are inactive on theserver. These are files which existed at the time of the image backup, but weresubsequently deleted and recorded by a later incremental backup.Restores new and changed files from the incremental backups.Note: If an incremental backup is performed several times after backing up animage, make sure that the Tivoli Storage Manager server’s backup copy group hasenough versions for existing and deleted files on the server so that the subsequentrestore image with incremental and deletefiles options will be able to delete filescorrectly.Related tasks“Backing up data using the Java GUI” on page 126You can back up specific files, entire directories, or entire file systems from thedirectory tree. You can locate the files you want to back up by searching orfiltering. Filtering displays only the files matching the filter criteria for yourbackup.“Performing an image backup using the GUI” on page 144If the Tivoli Storage Manager image feature is configured, you can create an imagebackup where the real volume is available to other system applications. Aconsistent image of the volume is maintained during the image backup.“Performing an image restore using the GUI” on page 170This topic explains the procedure that you use to restore an image of your filesystem or raw logical volume.Method 2: Using image backup with incremental-by-date imagebackupUse this method to perform image backups with incremental-by-date imagebackup.1. Perform an image backup of the file system.2. Perform an incremental-by-date image backup of the file system. This sendsonly those files that were added or changed since the last image backup to theserver.3. Periodically, perform full image backups.4. Restore your volume by performing an incremental restore. Ensure that youselect the Image plus incremental directories and files option in the RestoreOptions window before beginning the restore. This will first restore the mostrecent image and will then restore all of the incremental backups performedsince that date.142 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
