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

You can use these methods to view the available management classes and theirattributes:v GUI or Web Client: Select View Policy Information from the Utilities menu.v command-line client: Run dsmc query mgmtclass -detail.Note: During expiration processing on a Tivoli Storage Manager server, if anarchived directory is eligible for expiration, the server checks if any existingarchived files require the archived directory to remain. If so, the archived directoryis not expired and the Tivoli Storage Manager client updates the insert date on thearchived directory to ensure that the directory is not expired before the files underit.Binding management classes to filesBinding associates a file with a management class. When you back up a file for thefirst time, Tivoli Storage Manager binds it to either the default management classor the management class specified in your include-exclude list.If the backup copy group for the management class specifies keeping multiplebackup versions of the file, and you request multiple backups, the server alwayshas one active backup version (the current version) and one or more inactivebackup versions of the file. All backup versions of a file are bound to the samemanagement class and are managed based on the attributes in the backup copygroup.When you archive a file for the first time, Tivoli Storage Manager binds it to thedefault management class, to the management class specified in yourinclude-exclude list, or to a management class you specify when modifying yourarchive options during an archive.Archived files are never rebound to a different management class. If you changethe management class for a file using an include.archive statement, the archmcoption, or through a Tivoli Storage Manager GUI, any previous copies of the filethat you archived remain bound to the management class specified when youarchived them.If a file is deleted on the client system then that file’s inactive objects are notrebound.Refer to the IBM Tivoli Storage Manager Administrator’s Guide for your operatingsystem, for more information on how files and directories are associated withmanagement classes.Rebinding backup versions of filesRebinding associates a file or a logical volume image with a new management class.Backups of files are bound again to a different management class in the followingconditions. In each condition, the files (active and inactive) are not bound againuntil the next backup.vYou specify a different management class in an Include statement to change themanagement class for the file. The backups are managed based on the oldmanagement class until you run another backup.Chapter 9. Understanding storage management policies 237
