Setting System Variables for a Recovery Session

You can set system variables during a CI session to affect the recoveries that you

perform during that specific CI session. Once you have set a system variable during a

CI session, then the setting affects all recoveries performed during that session unless

you turn the setting off. You can perform recoveries from a different CI session and not

set the system variables if you do not want system variables applied to specific

backups.

The types of system variables that you can set for recovery includes:

• Preserving the backup date for recovered files and directories

• Setting the NetWorker time zone to match the HP STORE process

• Turning the parallelism attribute on and off

• Changing the name of the creator of the files

• Relocating files from one group or account to another

• Recovering files to your local logon group or account

Preserving the Original Backup Date

You can set the NSR_MPE_OLDDATE system variable to preserve the original backup

date of files and directories.

To preserve the original backup date on the recovered file, directory, or MPE volume

set directory accounting information file, enter the following system variable during

the current CI session:

: SETVAR NSR_MPE_OLDDATE_ON ""

You can also set this system variable from the POSIX shell:

$ export NSR_MPE_OLDDATE_ON=""

Setting the NetWorker Time Zone to Match the HP STORE Process

The HPSTORE runs in the Command Interpreter, which uses the time zone set for your

MPE client. NetWorker runs in POSIX, which by default uses Greenwich Mean time.

To correct a potential discrepancy between time zones, you must set the TZ variable.

Important: You should always have the TZ variable set when performing server-

initiated or client-initiated backups, or recovering files and directories with

NetWorker. For example, when you are recovering your files, you need to set the time

zone variable; otherwise the recover browse time will be in Greenwich Mean Time.

To set the time zone for recovery sessions, add the following system variable when you

start a CI session:

: SETVAR TZ "

EST5daylight

Note that the value EST5daylight is only an example; it might not be appropriate for

your time zone.

You can also set the TZ variable from the POSIX shell:

$ export T=

EST5daylight
