Questions regarding environment configuration are explained.
Q: How do I make a backup of a system disk that is managed with GDS? [EFI]
A
For procedures on how to make backups of file systems /(root), /usr and /var, which cannot be unmounted while the system is operating, see "7.4 Backing Up and Restoring System Disk" and "7.5 Backing Up and Restoring System Disk through Alternative Boot Environment [EFI]."
Q: How do I make a backup of a disk (other than a system disk) that is managed with GDS?
A
The backup of GDS's logical volume can be made in the same way as a physical slice. However, make sure you make a backup using the logical volume. For example, do not boot from the CD-ROM and make a backup using the physical slice, since correct data may not be saved.
You can also efficiently create a backup with the mirroring function. For details, see "1.3.8 Snapshots by Slice Detachment" "7.9 Backup (by OPC)" and "B.1.5 sdxslice - Slice Operations."
By making use of GDS Snapshot proxy volumes, you can also configure backup administration that minimizes operation stop time. For details, see "1.5 Proxy Volume," "3.15 Online Backup and Restoration Using Proxy Volume," " 7.7 Backup (by Slice Detachment)," and "7.8 Backup (by Synchronization)."
Furthermore, backing up data through a server outside the domain running the service using GDS snapshot shadow volumes can hold the effects on the service to a minimum. For details, see "1.6 Shadow Volume" and "3.20 Backing Up and Restoring through External Server."
Q: I cannot execute the command parted(8) on a physical disk managed by GDS (e.g. sda). How can I solve this problem?
A
Since access to physical disks is restrained by GDS, you cannot perform this operation.
For details, see "A.1 Restraining Access to Physical Special File."
If all you need to do with the commands parted(8) is to refer to the disk contents, you may do so by booting from the CD-ROM, and specifying the physical disk. However, you must exercise care since updating the data on the physical disk will damage the mirrored data. For details, see "A.2 Booting from a CD-ROM Device."
