db_archive [-alsVv] [-h home]
The db_archive utility writes the pathnames of log files that are no longer in use (for example, no longer involved in active transactions), to the standard output, one pathname per line. These log files should be written to backup media to provide for recovery in the case of catastrophic failure (which also requires a snapshot of the database files), but they may then be deleted from the system to reclaim disk space.
The options are as follows:
It is possible that some of the files to which the log refers have since been deleted from the system. In this case, db_archive will ignore them. When db_recover is run, any files to which the log refers that are not present during recovery are assumed to have been deleted and will not be recovered.
The db_archive utility uses a Berkeley DB environment (as described for the -h option, the environment variable DB_HOME, or because the utility was run in a directory containing a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, db_archive should always be given the chance to detach from the environment and exit gracefully. To cause db_archive to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).
The db_archive utility exits 0 on success, and >0 if an error occurs.
