Cold Backup
Cold backup refers to an external backup of the system taken when the database has been shut down normally. The backup is typically a backup of all file systems in use by the system. At a minimum, this includes all directories used by InterSystems IRIS in any way, including the installation directory, database directories, journal and alternate journal directories, WIJ directory, and any directory containing external files used by the database. This strategy may be appropriate for systems where InterSystems IRIS is typically shut down at night.
The following table lists the advantages and disadvantages of the cold backup strategy:
| Advantages |
Disadvantages |
|
Simple procedure (stop and copy entire instance). |
