ontape for Data Recovery

Use

ontape is one of a number of Informix tools for data recovery (that is, database archive, logical-log backup and restore) with your Informix database. ontape provides the following functions on both UNIX and NT platforms:

Archive database (but not selected dbspaces and not in parallel)

Back up logical-log files

Restore data from archives and backups (including restore of selected dbspaces)

You cannot perform unattended database archives and logical-log backups with ontape .

Integration

If you choose ontape as your data recovery tool, you must do all your database archives, logical-log backups, and restores with it.

Caution

The archives and backups written by ON-Bar , ontape , or ON-Archive are not compatible. You cannot mix tapes from these tools. Do not use one tool to back up the logical log and the other to archive the database.

Compared to the other tools available, ontape is easy to use but has limited functionality. For a wider range of functions, choose ON-Bar or ON-Archive as your data recovery tool. For more information about the differences between the Informix data recovery tools, see Comparison of ON-Bar, ON-Archive, or ontape for Data Recovery.
