Chapter 2 NAS Head 2-91

Local backup or restore fails with ?PNReduce error? in log.

This message indicates that StorEdge could not read the pathname (PN) provided

for backup or restore. The local backup and restore utilities require a full path, they

are case sensitive, and they do not allow the use of wildcards (?*? or ???). Specifying

a directory causes it to be backed up in its entirety.

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, access the

StorEdge CLI, as follows:

1. Connect to the StorEdge via Telnet, serial console, or keyboard console.

2. Type “admin” at the [menu] prompt and enter the administrator password.

3. At the CLI, enter “ndmp set dump.pathnode=yes”

4. Type “ndmp set tar.pathnode=yes”

5. Type “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 do so, proceed as follows:

1. Connect to the StorEdge via Telnet, serial console, or keyboard console.

2. Type “admin” at the [menu] prompt and enter the administrator password.

3. Enter “ndmp set ignore.ctime=yes”

4. Enter “ndmp save”
