Incremental backups on memory-constrained systems
Incremental backup performance suffers if the system has a low amount of memory available before starting the backup.
If your system is memory constrained, specify the memoryefficientbackup yes option in your client options file. This option causes the backup-archive client to process only one directory at a time, which reduces memory consumption but increases backup time. When you specify yes, the client analyzes only one directory at a time for backup consideration. If performance remains poor, check your communication buffer settings and the communication link between your system and the Tivoli® Storage Manager server. If your system is not memory constrained, setting the memoryefficientbackup option to yes degrades your backup performance.
