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.

{% hint style="info" %}
The RAM usage might increase when backing up to extra large backup sets (4 TB and more).
{% endhint %}

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