NDMP backup fails: access denied message.
NDMP software must authenticate to the StorEdge in order to backup files and
directories. Each NDMP software solution has a place to configure a username and
password for a device. For StorEdge, the username is “administrator”, and should be
accompanied by the console password.
NDMP: Can’t browse backup history.
Certain NDMP backup utilities are not able to browse backup history without a
configuration change on the StorEdge. To make this configuration change, it is
necessary to access the StorEdge CLI.
This behavior is configurable only at the Command Line Interface (CLI).
1. To access the StorEdge CLI, connect to the StorEdge via Telnet, and type “admin”
at the [menu] prompt and enter the administrator password.
2. At the CLI, enter “ndmp set dump.pathnode=yes”.
3. Then “ndmp set tar.pathnode=yes”.
4. Then “ndmp save”.
NDMP incremental/differential backups back up all files.
Some Windows applications, such as virus scanning software, update timestamps on
all files that they scan. NDMP software uses this same timestamp to identify
whether the file has been backed up since the last full backup. As a result, NDMP
sees all these files as modified, and effectively performs a full backup instead of the
desired incremental or differential.
To avoid this problem, it is possible to configure StorEdge to ignore this timestamp
when performing NDMP backup.
To access the StorEdge CLI, connect to the StorEdge via Telnet, and type “admin” at
the [menu] prompt and enter the administrator password.
From the command line enter:
ndmp set ignore.ctime=yes
ndmp save
