A save or res<strong>to</strong>re request is invoked through the GUI or through the CLI (DCL).<br />

IF the request is a . . . THEN the data is . . .<br />

Save request<br />

Res<strong>to</strong>re request<br />

Saved from online s<strong>to</strong>rage <strong>to</strong> the archive. An ABS catalog records<br />

the location of the saved data.<br />

Res<strong>to</strong>red back <strong>to</strong> online s<strong>to</strong>rage. ABS searches the catalog <strong>for</strong> the<br />

location of the data (archive), loads the appropriate volume, and<br />

res<strong>to</strong>res the data.<br />

2.2.3 <strong>Archive</strong>s<br />

An archive defines the media type and other characteristics where you can safely s<strong>to</strong>re data.<br />

Each archive has a unique name and contains a set of archive characteristics. You can simply reference<br />

an archive name in a save or res<strong>to</strong>re request rather than a complicated set of characteristics.<br />

<strong>Archive</strong>s are designed <strong>to</strong> be shared among many save or res<strong>to</strong>re requests.<br />

Each archive defines the following:<br />

• The type of archive <strong>to</strong> use (TAPE or DISK)<br />

• If the archive file system is TAPE, the media type, pool, and location <strong>for</strong> tape volumes in the<br />

archive<br />

• How long <strong>to</strong> keep the data s<strong>to</strong>red in a particular archive (retention period or expiration date).<br />

You can specify two archives <strong>for</strong> save requests that per<strong>for</strong>m both full and incremental operations<br />

(at different times) so that the full and incremental saves can have different retention<br />

periods and can reside on different volume sets<br />

• Who is allowed <strong>to</strong> access the archive (<strong>for</strong> data safety)<br />

• Who is allowed write data <strong>to</strong> and read data from the archive (ensures data safety)<br />

• Which catalog contains the in<strong>for</strong>mation about the data s<strong>to</strong>red in the archive<br />

• How long <strong>to</strong> use a volume set<br />

• How many save or res<strong>to</strong>re requests can be executed simultaneously<br />
