You perform an MPE/iX backup in the same way as the filesystem backup. For the procedure, see the online Help index: “creating backup specifications”.
Additionally, specify the supported MPE/iX backup options in the form of extended variables. See
User-definable backup variables
Set
Table 4 on page 30 lists backup variables and their values.
Table 4 List of backup variables
Variable | Value | Description |
ONLINE | none (default) | If this variable is used, files must be closed for |
|
| write access during backup. This provides |
|
| compatibility to |
|
| backup behavior. The TurboSTORE/iX log file logs |
|
| information about the files that could not be |
|
| backed up. This log is created during backup and |
|
| restore and is presented as |
|
| /tmp/storeprocessid.log. |
ONLINE | START | If this variable is used, files are not required to be |
|
| closed for write access during backup. If |
|
| ONLINE=START is not set, “open file” errors will |
|
| occur during backup. For more information, see |
|
| the TurboSTORE/iX documentation |
DIRECTORY | none (default) | Used to back up the MPE system directory |
|
| information, which keeps track of the accounts, |
|
| groups, users, and files (but not of the private |
|
| volume sets). Storing directory information helps |
|
| you rebuild your system from backups if you |
|
| unexpectedly lose information. All hierarchical |
|
| filesystem directories on the system are also stored |
|
| when DIRECTORY is specified. |
