While backing up, an agent typically consumes about 350 MB of memory (measured during a 500-GB volume backup). The peak consumption may reach 2 GB, depending on the amount and type of data being processed.
Bootable media or a disk recovery with a reboot requires at least 1 GB of memory.
A management server with one registered machine consumes 200 MB of memory. Each of the newly registered machines adds about 2 MB. Thus, a server with 100 registered machines consumes approximately 400 MB above the operating system and running applications. The maximum number of registered machines is 900-1000. This limitation originates from the management server's embedded SQLite.
You can overcome this limitation by specifying an external Microsoft SQL Server instance during the management server installation. With an external SQL database, up to 8000 machines can be registered without significant performance degradation. The SQL Server will then consume about 8 GB of RAM. For better backup performance, we recommend managing the machines by groups, with approximately 100 machines in each.
