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 15% disk space left.
2. If moving archives is not possible, NetDVR will attempt to delete the oldest archives. This will
happen if:
o
there is less than 10% disk space left, andthe available disk space goes below 30 GB plus
1.5 GB per camera
- or -
o
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 will not necessarily be considered to be running out of
disk space just because they have less than 10% disk space left.
IMPORTANT:
You will lose data from the archives being deleted.
2. Ultimately, if there are no archives to delete, NetDVR will attempt to resize camera databases by
deleting their oldest recordings. This will happen if:
o
there is less than 5% disk space left, andthe available disk space goes below 20 GB plus 1
GB per camera
- or -
o
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.
IMPORTANT:
You will lose the data deleted as part of the database resizing process.
When the recording server is restarted upon such database resizing, the original database sizes
will be used. You should therefore make sure the drive size problem is solved, or adjust camera
database sizes to reflect the altered drive size.
Tip:
Should the database resizing procedure take place, you will be informed on-screen in
NetGuard-EVS, in log files, and (if set up) through an e-mail and/or SMS alert.

Backing Up Archives
Many organizations want to back up recordings from cameras, using tape drives or similar.
Creating such backups based on the content of camera databases is not recommended; it may
cause sharing violations or other malfunctions.
Instead, create such backups based on the content of archives. If you have not specified separate
archiving locations for separate cameras, you could simply back up the default local archiving
directory,
Archives
.
When scheduling a backup, make sure the backup job does not overlap with your specified
archiving times.
