Automatic response if running out of disk space

If your system runs of disk space while archiving, you can set up an automatic response. Two scenarios can occur, depending on whether the camera database drive is different from, or identical to, the archiving drive:

Same drive: Automatic moving or deletion of archives if drive runs out of disk space

If your system server is running out of disk space, and the archiving drive is identical to the camera database drive, your system automatically does a number of attempts to free up space. Most of these attempts will result in the loss of your data from archives or databases.

First, the system attempts to move archives. You can only move archives if you use dynamic archiving, with which you can archive to several different drives. This happens if:
- there is less than 15% disk space left, and the available disk space goes below 40 GB plus 2 GB per camera
  - or -
- the available disk space goes below 225 MB plus 30 MB per camera. Example: with ten cameras, the server would be running out of disk space if the remaining available disk space went below 525 MB (225 MB plus 30 MB for each of the ten cameras).
The difference ensures that very large disks are not necessarily considered to be running out of disk space just because they have less than 15% disk space left.
If the system cannot move archives, your system attempts to delete the oldest archives. This happens if:
- there is less than 10% disk space left, and the available disk space goes below 30 GB plus 1.5 GB per camera
- or -
- the available disk space goes below 150 MB plus 20 MB per camera (example: with ten cameras, the server would be running out of disk space if the remaining available disk space went below 350 MB (150 MB plus 20 MB for each of the ten cameras))
The difference ensures that very large disks not necessarily are considered to be running out of disk space just because they have less than 10% disk space left.
If there are no archives to delete, your system attempts to resize camera databases by deleting their oldest recordings. This happens if:
- there is less than 5% disk space left, and the available disk space goes below 20 GB plus 1 GB per camera
- or -
- the available disk space goes below 75 MB plus 10 MB per camera (example: with ten cameras, the server would be running out of disk space if the remaining available disk space went below 175 MB (75 MB plus 10 MB for each of the ten cameras))
The difference ensures that very large disks will not necessarily be considered to be running out of disk space just because they have less than 5% disk space left.

When the system restarts your recording server after resizing the database, the original databases sizes are used, so you should make sure that the drive size problem is solved or, alternatively, adjust camera database sizes to reflect the altered drive size.

If the system performs the database resizing procedure, you are informed on-screen in XProtect Smart Client, in log files, and or in notifications (if set up).

Different drives: Automatic archiving if database drive runs out of disk space

In case the system server is running out of disk space, and the archiving drive is different from the camera database drive, and archiving has not taken place within the last hour, archiving automatically begins in an attempt to free up disk space. This will happen regardless of any archiving schedules. The server is considered to be running out of disk space if:

there is less than 10% disk space left, and the available disk space goes below 30 GB plus 1.5 GB per camera
the available disk space goes below 150 MB plus 20 MB per camera. Example: with ten cameras, the server would be running out of disk space if the remaining available disk space went below 350 MB (150 MB plus 20 MB for each of the ten cameras).

The difference ensures that very large disks are not necessarily considered to be running out of disk space just because they have less than 10% disk space left.

On the archiving drive, the system automatically checks that the space required for data from a camera to be archived plus 1 GB of free disk space per camera is available. If not, the archive drive's oldest data from the relevant camera is deleted until there is sufficient free space for the new data to be archived.
