Updated: 8/30/18 DATA INSURANCE Disasters are in the news, and it is easy to recognize the value of having the right insurance, Data Insurance. The HCL Informix Dynamic server implicitly provides you with some basic insurance by automatically maintaining physical and logical logs to provide data integrity should something abruptly stop the server. But that may not be enough when there is a disk failure, corruption, or a flooded server room. While HCL Informix support can help solve many problems, some problems can only be resolved by restoring from a backup. You may already have routine backups completely under control, but if not, now is the time to get started. Assuming you don't have any data insurance, you have three tasks: 1. Backup the HCL Informix Dynamic Server data 2. Backup the HCL Informix Dynamic Server Critical files 3. Continually backup the logical logs HCL Informix Server provides you two ways to back up your server without taking it offline: Ontape and onbar. The "ontape" utility can sequentially create an archive of the server's dbspace data in a tape, directory, or other removable media. The "onbar" utility support parallel archiving of the dbspaces and critical files, but requires the use of a Storage Manager, such as Tivoli Storage Manager, or you can use the HCL Informix Primary Storage Manager. The two archive systems are not interchangeable. |
