When STORE is Complete

Using NODECOMPRESS

Normally, when VSTORE veriﬁes a compressed store media, it reads in each record and

decompresses it. This results in a thorough veriﬁcation of the media by checking both the

integrity of the data on the media as well as the correctness of the compression algorithm.

If the NODECOMPRESS option is speciﬁed, VSTORE will only read the records from the media.

It will not decompress them. This veriﬁes only that there are no media errors on the

media. on the media. It also speeds up the VSTORE process, since it does not have to

perform the decompression.

This option should be used when the time to verify compressed store media is a prime

concern. In most cases, full veriﬁcation should be done to ensure that the data was

compressed and written without error.

The NODECOMPRESS option can only be used with VSTORE, for example:

:FILE T;DEV=TAPE

:VSTORE *T;@.@.@;SHOW;NODECOMPRESS

Retaining the STORE Tapes

Unload each backup and check for correct labeling. If you used the SHOW=OFFLINE option of

the STORE command, the system has printed a list of the ﬁles you stored. Retrieve the

report from your printer and either ﬁle it with your records or attach it directly to one or

more backup reels. Place each backup in your backup library.
