AdvancedCopy Manager backs up data in units of slices. A slice that stores work data is called a transaction volume.
A transaction volume to be backed up must reside on the ETERNUS disk storage systems.
For the supported units, refer to "1.5 Managing a Device on AdvancedCopy Manager".
For information on setting up a transaction volume, see "4.4.7 Setting the operation type for a device".
Note
Do not back up the systems disk or slices on which AdvancedCopy Manager is installed.
Slices must be allocated for transaction volumes in the following manner:
Create slices so that no VTOC is created.
No slice area may be duplicated on the same disk.
For any slice that defines an entire volume, do not register it as a transaction volume.
No file system of SynfinityFILE consisting of multiple slices and no Global File Services local file systems can be processed.
When backing up or restoring a file system of SynfinityFILE consisting of multiple slices or a Global File Services local file system, unmount the multiple slices at the same time.
Refer to the "11.1.1 General notes" for points to consider when deciding on a candidate volume for backup. Some points to consider include but may not be limited to:
