Figure 15: Local CIFS Backup - Same Device
In Figure 15, the administrator uses the ‘backup’ utility in the NSS GUI menu to select:
• The specific shares for which backup is required
• The frequency of the backup; and
• The target CIFS share on the local system where the backup file is to be written
When the system clock reaches the configured backup time, the system will select those
shares, concatenate them into a Tape Archive formatted file and compress that file using
GZIP. The compressed file is then written to the target device share.
In Figure 16, the target for the backup is another local NSS device within the CPE
infrastructure.

Figure 16: Local CIFS Backup - 2nd (or more) LAN attached NSS
Again in this example, the administrator uses the ‘backup’ utility in the Device’s GUI menu
to select the specific shares for which backup is required, the frequency of the backup and
the target CIFS share where the backup file is to be written However, this time the target
includes a Server name and associated user ID and password. When the system clock
reaches the configured backup time, the system will select those shares, concatenate them
into a Tape Archive formatted file and compress that file using GZIP. The compressed file is
then written to the target device share over the LAN.
