Data Loss Risks

Robot Save can protect you against the following risks. You should decide the magnitude of these risks based on your local conditions. The risks are listed in order of expected occurrence:

• An application or human error ruins an object.

• Your system loses one disk drive. Either the Auxiliary Storage Pool (ASP) or the regular drives are still working.

• Your system is destroyed.

• Your system and on-site tapes are destroyed.

• Your system and on-site tapes are destroyed and one copy of the backup tapes stored off-site cannot be read.

To protect yourself against these risks, you should back up your disk drives to tape regularly. Store at least two copies of the objects on your system off-site. You also should journal the changes to your important files onto an ASP.

Another risk of data loss occurs if your system loses power. Depending on machine activity, the system could lose all of the database changes for the last 2 to 30 minutes if power fails. Protect yourself by installing a UPS hardware system of appropriate size.
