Size of daily backups and NETflow data


You can easily check the size of daily backups directly from: Other Backups System. Based on empty space on disk and detected size of daily backups you can

easily determine the number of archived backups in turns (Settings System Settings Backups).


Size of daily system backups (Full backup - Daily):

  • Starting ISP: approx. 3GB/day
  • Bigger ISP after a few years of operation: approx. 12GB/day

icon info2 If you select Full backup - weekly - incremental backups are done and the size of each increment is significantly smaller. So you have to count with a total size of backups in individual backup sections.

You can use the same procedure for browsing directory structure of NETflow data: Other Backups Netflow. This way you will know the size and increment of stored data by NETflow module - this data is not backed up.
For more information - see NETflow module.

Size of NETflow data per month:

  • Starting ISP: approx. 5GB/month
  • The biggest ISP’s: approx. 20GB/month

Approximate size of binary backups of Mikrotik routers:

  • Usual binary backup: approx. 25kB
  • For main routers or shapers: approx. 5MB.
