Backup operations require about 1 GB of RAM per 1 TB of backup size. The memory consumption may vary, depending on the amount and type of data being processed by the agents.

The RAM usage might increase when backing up to extra large backup sets (4 TB and more).

On x64 systems, operations with bootable media and disk recovery with restart require at least 2 GB of memory.
