Backup of configuration data
You can back up configuration data while the system is online, but the MAS
must be offline before you can perform a restore operation.
The configuration data backup file contains the following files:
• an SQL database dump that contains data from the system configuration-
related database
• a text file that contains metadata for the load
• a text file that contains metadata for the schema versions
Restrictions
The backup zip file contains metadata that defines the complete load version,
for example, 5.0.193. You can perform restore operations only if the load
version metadata in the backup file is identical to the running load version.
Attention: You must create a backup file after any installation or upgrade to
ensure a compatible backup is available for restoration. If you do not create
a backup file, you cannot restore the currently running version.
Service data (Content Store data)
You can back up service data while the system is online, but the MAS must be
offline before you can perform a restore operation.
The service data backup file contains the following files:
• an SQL database dump that contains data from the Content Store-related
database
• a zip file of all files on disk in the managed storage area of the Content
Store
• a text file containing the metadata for the load
• a text file containing the schema versions
Restrictions
The backup zip file contains metadata that defines the complete load version,
for example, 5.0.193. You can perform restore operations only if the major load
version in the backup file matches the running major load version. Minor
version, load build number, and schema version are not considered.
Attention: You must create a backup file after any installation or upgrade to
ensure a compatible backup is available for restoration. However, unlike
configuration data, you can perform a restoration from a noncompatible
backup file only if you perform an upgrade from a previous release or the
major load version is 5, for example MAS 1.0.193.
