Unscheduled System Backup

Unscheduled System Backup

    SCO Unix Release 3.2v5.0.0

    This section describes how to perform an unscheduled backup. This type of backup covers an entire filesystem. Most Unix systems have multiple filesystems. Each filesystem should be backed up. Each filesystem must be backed up on it’s own set of tapes.

    You should have more than one series of tapes to alternate your backups. You should also keep a manual log of when the backup was done and on which series of tapes.

    Your “daily” unattended backups only backup your applications, they do not backup the operating system. Unscheduled backups should be done periodically to ensure that the operating system is backed up.

    1. Login as root
    2. At the # sign type in scoadmin

Enter the number in kilobytes the tape is capable of backing up uncompressed. If you are not sure of the number call Island Systems for assistance. Example; if the tape can backup 2 gigabytes then the number in KBytes would be 2000000 (2million). Press to highlight [APPLY], Press . Highlight [OK], press . Highlight [CLOSE] press .
