The NSRRECOV Program

You can start the NSRRECOV program from the MPE/iX Command Interpreter

(CI) or from the POSIX if you prefer.

You can only recover ﬁles that you have previously backed up. You can start

the NSRRECOV program from any directory; however, if you start it from a

directory that has not been previously backed up by NetWorker, then

NetWorker prompts you to enter the name of the save set that you want to

browse. The NSRRECOV program is an interactive, browse recovery

procedure.

During both an interactive and noninteractive recovery, if you try to recover a

ﬁle, directory, or an MPE volume set directory information ﬁle that already

exists, NetWorker tells you that the ﬁle exists. NetWorker prompts you and

gives you the options of discarding the recovered ﬁle, overwriting the existing

ﬁle with the recovered ﬁle, or renaming the recovered ﬁle.

You can turn the overwrite prompt off and set the NSRRECOV program to

consistently overwrite existing ﬁles or consistently not overwrite existing ﬁles.

Setting this system variable also turns on the parallelism attribute. The

parallelism attribute allows any one recovery session to be executed faster by

having two or more recovery subprocesses work concurrently.

To turn the prompts off and recover the ﬁles in parallel, you enter the

NSRRECOV command, the regular NSRRECOV program parameters, and

either -iY or -iN. If you enter -iY, the i turns on the parallelism and the Y

overwrites any existing ﬁles. If you enter -iN, the i turns on the parallelism and

the N instructs the NSRRECOV program not to overwrite any existing volume

sets.

If you turn on parallelism, then you can set a system variable to turn it off

again. See “Turning Off Parallelism” (on page 29).

The NSRRECOV command to start the NSRRECOV program has the

following parameters:

• -s, the server parameter

• The name of the server from which you are recovering the ﬁles

• -c, the client parameter

• The name of the client to which you are locating the recovered ﬁles.

• -iY, which turns overwrite prompt off; consistently overwrites existing

ﬁles, directories, or MPE volume sets directory information ﬁles; and

turns parallelism on.
