Info

||||||||||||||||||||||||||||Notes:1. Journal-based backup is supported on a Version 5.2 or higher Tivoli StorageManager server.2. When using anti-virus software, there are limitations to journal-based backup.3. A journal-based backup might not fall back to the traditional incrementalbackup if the policy domain of your node is changed on the server. Thisdepends on when the policy set within the domain was last updated and thedate of the last incremental backup. In this case, you must force a fulltraditional incremental backup to rebind the files to the new domain. Use thenojournal option with the incremental command to specify that you want toperform a traditional full incremental backup, instead of the defaultjournal-based backup.Considerations: Under the following conditions, the journal database isconsidered invalid and the client reverts to the traditional full incremental backup:v A journaled file space name has changed.v The client node name has changed.v The client contacts a different server to do the backup.v Policy changes have occurred (new policy set activation).v The journal is corrupt (out of space conditions, disk error).v The journal is not running.Journal-based backup differs from the traditional full incremental backup in thefollowing ways:v Tivoli Storage Manager does not enforce non-default copy frequencies (otherthan 0).v Changes to UNIX special files are not detected.You can use the nojournal option with the incremental command to perform atraditional full incremental backup instead of the default journal-based backup. See“Nojournal” on page 299 for more information.Incremental-by-DateAn incremental-by-date backup backs up new and changed files with amodification date later than the date of the last incremental backup stored at theserver, unless the files are excluded from backup by an exclude statement.||If an incremental-by-date is performed on only part of a file system, the date of thelast full incremental is not updated, and the next incremental-by-date will back upthese files again. Changes to the access control lists (ACL) or Extended Attributesdo not cause the files to be backed up during an incremental-by-date. Use thequery filespace command to determine the date and time of the last incrementalbackup of the entire file system.To perform an incremental-by-date backup, use the incrbydate option with theincremental command.Unlike a full incremental, an incremental-by-date does not maintain current serverstorage of all your workstation files because:v It does not expire backup versions of files that are deleted from the workstation.v It does not rebind backup versions to a new management class if themanagement class has changed.v It does not back up files with attributes that have changed, unless themodification dates and times have also changed.v It ignores the copy group frequency attribute of management classes.432 IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
SupportedSyntaxFor these reasons, if you have limited time during the week to perform backups,but extra time on the weekends, you can perform an incremental-by-date backupon weekdays and a full incremental backup on weekends to maintain currentserver storage of your workstation files.If the incremental command is retried because of a communication failure orsession loss, the transfer statistics will display the number of bytes Tivoli StorageManager attempted to transfer during all command attempts. Therefore, thestatistics for bytes transferred might not match the file statistics, such as those forfile size.Associating a local snapshot with a server file spaceUse the snapshotroot option with the incremental command in conjunction with athird-party application that provides a snapshot of a logical volume, to associatethe data on the local snapshot with the real file space data that is stored on theTivoli Storage Manager server. The snapshotroot option does not provide anyfacilities to take a volume snapshot, only to manage data created by a volumesnapshot. See “Snapshotroot” on page 351 for more information.ClientsThis command is valid for all UNIX and Linux clients.►►Incrementaloptions▼filespec″filespec″►◄Parametersoptions|Table 78.
