Storix System Backup Administrator 66 Version 8.2 Linux System Recovery Guide
7. Install the System
To install the system from the
SBAdmin System Backup , you first must have selected the Installation Device
(which may be located on a local or remote host). You then have the option View/Change the Installation
Settings , where you can make any changes to the backup information stored on the backup media. If you used
that option, then the backup information was already restored from the backup, verified and modified as needed
to ensure the installation can be started.
Verification Process
If you select the option Install the System with Current Settings, this backup data will be checked (again if
necessary) to ensure the defined devices and filesystems can be created successfully. Here are a few things
that are checked:
1. The devices and filesystems defined on the backup are checked to ensure the kernel and modules
available from the boot media are adequate to create them. This includes ensuring that LVM and the
various RAID levels are available if required.
2. Ensures any backup data previously residing on a disk is assigned to a new disk unless the user
explicitly chose not to restore data.
3. Verifies that all devices assigned to meta-disks are valid and that there are enough devices assigned
for the appropriate RAID level.
4. Verifies that the physical volumes assigned to both volume groups and logical volumes are valid.
5. Checks that volume groups are large enough to hold the logical volumes defined.
6. Verifies physical volumes assigned to logical volumes are adequate for striping, if defined.
7. Validates the partition table and automatically adds an extended partition if needed to allow future
expansion into logical partitions. This is important also since the backup may be installed onto larger
disks, and using all primary partitions would prevent the ability to expand onto them.
8. Verifies that partitions will fit onto their respective disks and that primary partition sizes are defined at
disk track boundaries (in case the disk geometry has changed).
9. Checks that all filesystems are being created on devices large enough to restore the data. Even if a
device has not changed, the requirements may change if, for instance, the filesystem type was
changed to one which requires more space for filesystem metadata than was previously needed.
10. Verifies that the root filesystem is being restored and the device on which it is defined is still valid.
11. Verifies that the configuration conforms to boot loader requirements of the specific system type.
If any problems are detected, you will be informed of the problem and a recommended solution. In some cases
the process will offer to fix the problem for you. If problems persist, you will need to return to the
Change
Settings menu to make any changes required to restore the data.
