In addition to administering the database server, you can tune performance, replicate data, and archive data.
Backup and Restore Guide
The Informix® Backup and Restore Guide describes how to use the Informix ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

Changing storage-manager vendors
If you change storage manager vendors, do not remove the old storage manager until you have proof that the new storage manager works for both backup and restore operations. You can use the old storage manager as a backup storage manager to use in case the new storage manager does not meet your needs.

      - Backing up before a database server or storage-manager upgrade
        Before you upgrade to a new version of the database server, you must perform a complete backup.
      - Upgrading a third-party storage manager
        If you upgrade a third-party storage manager vendors, do not remove the old storage manager until you verify that the new storage manager works for both backup and restore operations.

      - Switching from ontape to ON-Bar
        You cannot back up data with ontape and restore it with ON-Bar, or conversely because the data storage formats and backup capabilities are different. However, you can back up data with ontape, prepare to use ON-Bar, and then back up with ON-Bar.

  The HCL® Informix® Enterprise Replication Guide describes the concepts of data replication using Informix Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.

Changing storage-manager vendors

If you change storage manager vendors, do not remove the old storage manager until you have proof that the new storage manager works for both backup and restore operations. You can use the old storage manager as a backup storage manager to use in case the new storage manager does not meet your needs.

ON-Bar supports working with multiple storage managers at the same time. To set up to test one storage manager and keep the other as a backup storage manager, specify information for both of the storage managers in the BAR_BSALIB_PATH configuration parameter and in the $INFORMIXDIR/etc/sm_versions file.

If you cannot use the old and new storage managers at the same time, use ON-Bar and the Informix® Primary Storage Manager or ontape as an alternative for backups while you check that backup and restore operations work correctly with the new storage manager. Until you confirm that the new storage manager works correctly, perform all your backups as whole system level-0 backups (onbar -b -L 0 -w)

If you change physical connectivity, such as moving a storage device from a local connection to a network server, make sure the new storage manager can move the data across the network. Also ensure that the new storage manager can send multiple data streams to storage devices. It also might use a different version of XBSA.
