2. Create a shared folder on each Server and make sure \\server\share is accessible through the network.
3. Go to Server Settings and add all shared folders as NAS devices (see "Configuring Server Storage/NAS").
4. Click Use as backup storage on each one added.
5. Setup backup parameters (described below).
6. Repeat the above steps on all servers.
Therefore, each server will be backing up the footage to all other servers in the system. This will reduce the overall
amount of stored footage but increase redundancy.
The backup options are active if at least one storage is used as backup:
Backup Archive From – select Cameras to backup footage from. By default all devices are being backed up.
Backup Quality – select specific streams (Hi-res or Low-res) if bandwidth saving is necessary
Server Backup Settings provides several different backup modes:
Real-Time – backup will be performed immediately: the footage will be written to the main and backup
immediately and simultaneously. If there is insufficient bandwidth to write to a network location, user will see the
corresponding warning. Previous data is not backed up in this case.
By Schedule – backup will be performed on specific days of week and specific hours. Only previous data is backed
up in this case. Note that the footage will be backed up since the last time backup finished (or since the very
beginning if this is the first time backup occurs). If the network bandwidth is insufficient, the backup may not be
fully completed within the time frame given. For instance, if backup is performed once a week for 1 hour and tries
to back up footage from 100 cameras, it will be able to backup only several hours. The date and time of the footage
that is backed up will be clearly indicated on the bottom part (Archive backup complete until...).
On Demand – backup occurs only if User presses Start Backup Now and continues until completion (that means all
previous data is backed up) or until it's canceled. Only previous data is backed up in this case.
When archive Backup is finished, the corresponding Event is triggered. See "Archive Backup Finished".
