Adjust the Reserved Disk Space

What is reserved disk space?

By default, Nx Witness reserves free space for every single local disks and network shared drives.
Nx Server will start recycling the oldest footage as soon as free space of the disk is less than assigned reserved space.

What is the size of reserved space?

The reserved space is 10 ~ 30 GB for each local drive and 50 ~ 100 GB for each NAS on an Nx Server, but not greater than 10% of a drive total size in both cases.

Can I change the size of reserved space?

Some users might want to reasonably change the size of reserved space because of some user's requirements and need to keep larger space for longer retention days. In Nx Witness, this can be configured via the following steps:

1. Open the Web Admin.
2. Navigate to the Settings menu.
3. Click on Servers.
4. Add ?advanced= to the URL and hit enter. The URL will look like this:

   https://<serverIp>:port/#/settings/servers/<serverId>?advanced=

   For example:

   https://localhost:7001/#/settings/servers/ff72f898-3067-2685-87a6-1b2e96fabc49?advanced=

5. Scroll down and enter the desired value in the Reserved space field to meet your use case.
6. Click Save.
