Tuning memory

You can tune the client to use less memory during incremental backup operations.

Client memory requirements and ulimit settings for incremental backups
The amount of memory that is used for normal incremental backups is proportional to the number of files that are being examined for backup. When you start an incremental backup operation that backs up numerous files, one way to prevent the client from running out of usable memory is by setting the operating system ulimit data value (ulimit -d) to unlimited.
Reduce client memory use
The memoryefficientbackup client option determines how much memory the client uses during incremental backup operations. Restricting the amount of memory that the client can use during incremental backups reduces the efficiency of incremental backup processing. The default setting for the memoryefficientbackup option is no, which does not limit the memory that the client can use.
