Figure A-2: NAS setting
Note: One NAS can connect multiple DVR hosts, in order not to confound
the back-up data, their folders’ names should be different.
6.User: Fill in the login user account on NAS.
7.Password: Fill in the password for the corresponding user.
8.Overwrite: If you want to recycle your backup NAS storage when
storage is full, click the ‘’Overwrite’’ checkbox to enable it. Once
overwrite enabled, NAS will initiate deleting files. The deletion will be
based on the free space lesser or equal to the Lowerbound. This
procedure will be continued till the free space is more or equal to the
Upperbound.
9.Backup Period: DVR will not keep archiving data to NAS, the ‘’
Backup Period’’ is the time interval to make sure NAS synchronized
with the DVR and backup new data to NAS. (In default, the system
will auto backup data every 1 minutes.)
10.Volume: “Volume” is the total available space for your DVR
backup.(NAS can backup the data of various DVR hosts, and here we
refer to the available space of your DVR can have).
EX: when Volume set up as 10G, Upperbound 400MB, Lowerbound
200MB. Once the free space on NAS lesser than 200MB, system will
delete the oldest files, till the free space more than 400MB.)
