For example, to enable the system to copy recording data automatically to remote
storage device at 01:15 every Monday, please do the following:

and select “Monday”.
5. Backup Options
z Select “Replication Now”, the system backs up recording data to remote
storage device immediately.
z Select “Overwrite the oldest recordings when the available storage on the
remote host is less than 4GB”; the system overwrites the oldest recording data
when the free space on the server is less than 4GB.
z Select “Perform mirroring replication by deleting extra files on the remote
replication”, the system syncs the recording data between VioStor and the
remote storage device and delete any extra files on the remote destination.
z When the above options are all checked, the system executes remote
replication immediately. It first judges if there are extra files on the remote
location that are different from the local source. If yes, the extra files will be
removed. After that, the system executes recording data backup and verifies
if the free space of the internal hard disk drive is less than 4GB. If the free
storage capacity is larger than 4GB, remote replication will be executed
immediately. If the free storage space is less than 4GB, the system deletes
the recording data of the oldest day and executes remote replication.
