Restoring customer data from tape
The Restore command can be used to restore customer data from a
backup tape in the event of a disk crash or other data corruption. This
process loads backup copies of the CC MIS database from a tape and
replaces existing databases.
Therefore, this procedure should be performed only if the existing data
has been corrupted or is no longer valid.
This procedure restores the following information from tape:
• definitions database for selected partitions
• data database for selected partitions (not applicable for NAPs)
• configuration database
Constraints
You can restore data from a backup tape only when the CC MIS soft-
ware is operating.
Corrupted data
Be sure that the software release of CC MIS used to
create your backup tape matches the software re-
lease of CC MIS that restores the data. Data will be
corrupted and the system may not function as de-
signed if the releases do not match.
Improper database size
When restoring a database from a backup tape, the
size of each partition's historical database on the
backup tape must be the same size or smaller than
the configured storage limit.
Restoring a backup that was performed prior to
hardware changes (for example, removing a disk)
may result in configuration problems.
Note:
The system will not allow a
backup tape created on
another CC MIS release to be
restored onto the 5.0
system.
