The difference between a normal restore and a full system restore is the severity of the problem. Normally, if data is lost or removed, it is recovered from the archives using the normal restore procedures. However, when a normal restore operation cannot correct a software and/or hardware corruption problem, some additional changes may be required.
When the root file system is lost, a full system restore is required.
Before You Begin
The full system restore operation for a Linux system includes the following general steps. Detailed instructions are provided in the following section.
This recovery procedure is for basic systems without MetaDisks or Logical Volume Management software. |
For this procedure, you must use a default installation of Linux. |
Try to avoid the unconditional overwrite of the root directory on a live file system. This is a mechanism that allows an unconditional overwrite of open files in the root directory (/) on a live file system. Performing such a restore can result in an inconsistent system that may also fail to boot. Use this option AT YOUR OWN RISK. |
To
perform a full system restore:
If you install the default install on an external drive, it can be used for other systems. However, you will have to remove and re-install the Linux File System iDataAgent software for each client. In addition, you will have to reconfigure TCP/IP, hostname, and domain name settings for each system. |
Use restored or saved data to obtain the information needed to repartition and label the new disk(s). |
Do not select Unconditional Overwrite from the Restore Options dialog box. |
The procedure is now complete.
If you have installed to a new server where the mount points may be different, be sure to edit the fstab and mtab files in the restored /etc directory to match the new server; also, be sure to edit the /boot/grub/menu.lst file to match the new configuration. Also, if there are hardware changes, be sure to reboot to single user first so that you can add new drivers to the operating system if needed. |
