Database backup
A Rational Synergy
database has two portions: Metadata, which is held in Informix®, and file system data. To protect
your data, you must back up both portions of your databases regularly.
Backing up databases for UNIX
Because the data stored in Rational Synergy databases is critical,
you must perform routine backups. If there is ever a major system
failure (such as disk crash), your Rational Synergy
database backup might be your only means of recovering your data.
Use the ccmdb backup command to ensure reliable backups
of Rational Synergy databases.
This command was designed to ensure that the database metadata and
the storage root (st_root) subdirectory in the backup
are synchronized.
Database packing
Packing individual databases is the preferred backup method.
This method creates a pack (.cpk) file that contains
a complete backup of both the file system and metadata portions of
your database.
Database dump method
If your database is large or takes too long to pack, dumping
a database is the preferred backup method. This method creates a dump
(.dmp) file containing only the database metadata,
instead of producing a pack file that contains the file system data
as well as the metadata.
