Info

Options FilePlace this option in the dsm.sys file. You can set this option on the Scheduler tab,Maximum command retries field of the Preferences editor.Syntax►► MAXCMDRetries maxcmdretries ►◄ParametersmaxcmdretriesSpecifies the number of times the client scheduler can attempt to process ascheduled command that fails. The range of values is zero through 9999; thedefault is 2.ExamplesMemoryefficientbackupOptions file:maxcmdr 4Command line:-maxcmdretries=4This option is valid only on the initial command line. It is not valid in interactivemode.The memoryefficientbackup option specifies the memory-conserving algorithm touse for processing full file space backups. One method backs up one directory at atime, using less memory. The other method uses much less memory, but requiresmore disk space.Use the memoryefficientbackup option with the incremental command when yourworkstation is memory constrained. You can also use this option as a parameter tothe include.fs option in order to select the algorithm Tivoli Storage Manager useson a per-filespace basis.If the memoryefficientbackup option appears in the option file, its value will beused for all file systems not represented by an include.fs option containing thememoryefficientbackup parameter. If a directory-level incremental is beingperformed, and memoryefficientbackup=diskcachemethod is present,memoryefficientbackup=yes will be used.Use memoryefficientbackup=diskcachemethod for any file space that has too manyfiles for Tivoli Storage Manager to complete the incremental backup with either thedefault setting, memoryefficientbackup=no, or with memoryefficientbackup=yes.The actual amount of disk space required for the disk cache file created by diskcache incremental backups depends on the number of files and directories includedin the backup and on the average path length of the files and directories to bebacked up. For UNIX and Linux estimate 1 byte per character in the path name.For Mac OS X, estimate 4 bytes per character in the path name. For example, ifthere are 1 000 000 files and directories to be backed up and the average pathlength is 200 characters, then the database will occupy approximately 200 MB for348 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
UNIX and Linux, and 800 MB for Mac OS X clients. Another way to estimate forplanning purposes is to multiply the number of files and directories by the lengthof the longest path to establish a maximum database size.A second disk cache file is created for the list of migrated files when backing up anHSM managed file system. The combined disk cache files, created by disk cacheincremental backups and HSM managed file system backups, can require above400 MB of disk space for each million files being backed up.Supported ClientsThis option is valid for all clients. The server can also define this option.Options FileThis option is allowed in both dsm.sys and dsm.opt, but the value in dsm.opt isignored if it also appears in dsm.sys. You can also place this option within a serverstanza, or on the initial command line. You can set this option on the PerformanceTuning tab, Use memory-saving algorithm check box of the Preferences editor.Syntax►►MEMORYEFficientbackupNoYesDISKCACHEMethod►◄ParametersNo Your client node uses the faster, more memory-intensive method whenprocessing incremental backups. This is the default.YesYour client node uses the method that requires less memory when processingincremental backups.DiskcachemethodYour client node uses the method that requires much less memory but moredisk space when processing incremental backups for full file systems.ExamplesOptions file:memoryefficientbackup yesmemoryefficientbackup diskcachemCommand line:-memoryef=noRelated information“Include options” on page 332Chapter 10.
