Virtual disaster recovery for Linux (beta)
Virtual disaster recovery for Linux is currently in beta. All users are welcome to try the feature and share improvement suggestions.
At the moment the feature is working for CentOS 5 and 6. You can initiate recovery from the same system that is being recovered or from a different one (CentOS 5 or CentOS 6).
The virtual disaster recovery of Linux systems is performed to virtual disk files (VMDK) created in a local directory. Their number depends on the number of hard drives in the source system.
For your convenience, a VMX file is created in the same directory. You can open this file with VMware Player/Workstation.
Preparing the source system for recovery
To start using the virtual disaster recovery feature for Linux, you should do the following:
- Install the Backup Manager.
- Perform the backup of the following data sources:
- Linux system state: the whole selection
- Files and folders: the whole
rootdirectory. You might be tempted to deselect some system directories like
/var/run, which contain files that are not exactly needed in a restored virtual machine. It is not advisable to do that (otherwise the restored virtual machine may not boot correctly).
- (optionally) Files and folders: user directories and any other.
None of the system partitions should be encrypted (otherwise virtual disaster recovery cannot be completed).
- Start the Backup Manager.
- Click Restore > Virtual Disaster Recovery.
- Select data to recover. A full selection is recommended (this will ensure that the recovered virtual machine can boot correctly).
- Specify the location of the directory to recover your Linux system to.
- Click Restore to start a recovery process.
- Hold on till the recovery process is completed. Its duration depends on the size of the system you are restoring, the data transfer speed, and the performance of your computer.
