Path : The path is effectively a pathname of a resource and corresponds to a series of FTP
commands, such as a directory tree:”ftp://jon:apple@bigcompany.com”. The applicable alpha-
numeric characters are [0-9][a-z][A-Z][-][/][_], with a max. length of 64 characters. If not specified,
destination will be the root directory.
Authorization: Click to enter user name and password for the FTP site. Click the Test FTP button to
test a connection with the FTP server. The applicable alpha-numeric characters are [0-9][a-z][A-Z]
[-], with a max. length of 64 characters.
Daily backup time: Default is 2:00 AM. Click to reveal the pull-down menu to specify a time when
the daily backup will take place, such as that system can perform the backup in the off-office hours
when network load is lower.
Backup Recording: Select the Recording cameras each by a single click. The recorded videos from
the selected cameras will be backed up according to your configuration.
Enable : Default is not selected. The scheduled backup function is not enabled by default. You must
click to enable the configuration options.
Type : Currently the NVR supports the backup to an FTP server.
Enter the Static IP, domain name, and other parameters for access to an FTP server.
Site : the fully qualified domain name of a network host, or its IP address. The max. length is 253
characters. Note that hyphen “-” cannot be used at the beginning or the end of the address.
Port : The port that the remote FTP server listens on. The default ports (which are the most
commonly used) are 21 for standard FTP and explicit FTPS, 990 for implicit FTPS and 22 for SFTP
via SSH. If necessary, change the port number. The range is 1 ~ 65535.
If the FTP backup errors occur, the system will retry the connection every 5 minutes until the connection
is remade or cancelled. Error messages will display on every failed attempt. For errors not related
to connection problems, retry takes place every 3 seconds for 5 times for each recording file. Error
messages will display on every failed attempt.
In the event of backup failures, failures will be recorded into system logs. The possible causes can be:
1. The previous backup is not finished when the succeeding backup starts, due to very slow upload
speed or network problems.
2. The on-going sheduled backup is cancelled.
3. Errors occur on the storage volume while the backup is taking place. For example, when the hard disk
is disconnected, formatted, or the system detects an unconfigured volume.
4. Path errors. The destination directory does not exist.
Upload limits : If network bandwidth is of the concern, enter an upper threshold for the bandwidth.
