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 a time, using less memory. The othermethod uses much less memory, but requires more 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.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 disk cache file created by the initial disk cache incremental backup can requireup to 5 gigabytes of disk space for each million files or directories being backedup.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. Estimate 2 bytes per character in the path name. For example, if thereare 1 000 000 files and directories to be backed up and the average path length is200 characters, then the database occupies approximately 400 MB. Another way toestimate for planning purposes is to multiply the number of files and directoriesby the length of the longest path to establish a maximum database size.Supported ClientsThis option is valid for all clients. The server can also define this option.Chapter 12. Processing options 413
