db4.4_hotbackup(1)
NAME
- db4.4_hotbackup - Create "hot backup" or "hot failover"
- snapshots
SYNOPSIS
db4.4_hotbackup [-cuVv] [-d data_dir ...] [-h home] [-l log_dir] [-P password] -b backup_dir
DESCRIPTION
Arrayuse DB_TXN->prepare should specify DB_RECOVER_FATAL when opening
the environment, and run DB_ENV->txn_recover to resolve any pending transactions, when failing over to the hot backup.
OPTIONS
-b Specify the target directory for the backup.
- ArrayThe db4.4_hotbackup utility uses a Berkeley DB environment
- (as described for the -h option, the environment variable
DB_HOME
- a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, db4.4_hotbackup
should always be given the chance to detach from the environment
and exit gracefully. To cause db4.4_hotbackup to release all environment resources and exit cleanly, send it an interrupt signal
(SIGINT).
The db4.4_hotbackup utility exits 0 on success, and >0 if - an error occurs.
ENVIRONMENT
Arraydatabase home, as described in DB_ENV->open.
