Preparing Storage Devices

Preparing Tape and DDS Devices

uses a total of four devices divided into two device pools.

:FILE PPA1;DEV=7

:FILE PPA2;DEV=8

:FILE PPB1;DEV=9

:FILE PPB2;DEV=11

:STORE @.OPERATOR.SYS;;STORESET=(*PPA1,*PPA2),(*PPB1,*PPB2)

If you gave the backup devices a single ﬁlename such as:

:FILE T;DEV=TAPE

enter the following STORE command to copy ﬁles to a set of parallel device pools:

:STORE @.@.@;;STORESET=(*T,*T),(*T,*T)

Using $NULL as a STORE Device

The devices speciﬁed for a backup can also refer to $NULL. This essentially does the backup

to the "bit bucket" -- no data is stored to any backup media. This type of backup can be

done by specifying a ﬁle equation prior to performing the backup. Instead of specifying a

tape device, specify $NULL. For example:

FILE N=$NULL

Doing so causes STORE to use $NULL as its output device. The command line is parsed, the

input ﬁleset scanned, all ﬁles are read from disk, and all output is displayed as normal.

The only real difference is that the data is not actually being written to an output device.

This feature can be useful when trying to determine which ﬁles will be stored by STORE,

as a trial run. It can also be used, with EXTREME caution, with the ;PURGE option, to

remove all speciﬁed ﬁles.

When using this feature, keep in mind that your ﬁles are NOT being stored to any device,

so the data has not been saved anywhere.

Using Remote Devices for Backups

STORE and TurboSTORE now support remote backup devices for storing and restoring

ﬁles. This feature, which was previously only available using CMSTORE, allows you to

specify a backup device, or devices, on a remote system for your backups. A connection to

the remote system must exist before the STORE is invoked. Once the remote connection is

established, a ﬁle equation should be created to point to the remote device. For example, to

store to a tape drive on the remote system BROWNY, issue the following FILE command:

FILE REMOTE;DEV=BROWNY#TAPE

This ﬁle equation can then be used as the device ﬁle argument to STORE, RESTORE, or

VSTORE, or can be used with the STORESET or RESTORESET options. For example, using the

ﬁle equation deﬁned above, the following STORE command will back up ﬁles to a remote

tape drive on BROWNY:

STORE @.@.@;*REMOTE;SHOW

Although the initial console device request will appear on the console of the remote system,

all further STORE console messages will be sent to the local system's console. These
