Database server archive and restoration for Informix

Archiving and restoring the server is the most complex—and the most difficult—way to back up and restore databases. Do not use the server archive and restore commands unless you are familiar with database logging techniques and neither of the methods discussed previously is practicable in your environment. Because the administrative complexities of this backup method are considerable, it might be more cost effective for you to invest in hardware solutions for high availability, such as RAID. Also, use one of the other backup methods to protect against complete system failure and satisfy other backup requirements.

A server archive creates an archive (9) file containing only the metadata for the server database. It does not produce a pack file that contains the file system data and the metadata. Also, it does not produce a dump file that contains metadata for a single database.

The only significant advantage to server archive is that it enables incremental or even continuous online backup of the metadata.

You cannot use a server archive to upgrade to a new release of Rational® Synergy.

The ccmdb backup command backs up individual databases. You can, however, back up the database server, and all its databases, using the ccmsrv archive command.

For InformixFor more information about the ccmdb backup command, see ccmdb backup.

Use the ccmsrv archive command under the following circumstances:

Before archiving your server, you also must:
