 ### Backups on the OT network sensor
 
 The retention of backup files depends on the sensor's architecture, as each hardware profile has a set amount of hard disk space allocated for backup history:
 
 | Hardware profile  | Allocated hard disk space  |
 |---------|---------|
-| **L100**     |  Backups aren't supported       |
-| **L500**     |  20 GB   |
+| **L100**  |  Backups aren't supported |
+| **L500**  |   20 GB  |
 | **E1000** |   60 GB  |
-| **E1800**       |   100 GB |
-| **C5600**       |   100 GB |
+| **E1800** |   100 GB |
+| **C5600** |   100 GB |
 
 If the device can't allocate enough hard disk space, then only the last backup is saved on the on-premises management console.
