Automatic Backups
During normal operations, files in system memory, on disk, and on tape can
become inconsistent (for example, when translations are changed, when
announcements are saved). During daily scheduled maintenance, several
actions are take to keep data files consistent:
1. At the start of scheduled maintenance, translations and error logs are
saved. This step must be enabled by the ‘‘Save Translation’’ field on the
change system-parameters maintenance
form.
2. Disk files are backed up to tape.
3. STO-DATA tests are run along with other daily maintenance tests.
At the end of this sequence, disk and tape files should all be identical, and
translations and error logs files should be current with system memory.
Announcement files are not saved automatically, and should be manually saved
after recording or altering announcements. The automatic backup will however
transfer these from disk to tape.
File Inconsistencies: Causes
A number of things can cause files to become inconsistent between devices.
Test stored data and list configuration software can be used to identify which
files are affected. Described below are some of the causes of inconsistencies.
