System state recovery requirements for Linux

Backup requirements

• The system backup session must be successful to restore the rescue ISO image.

• All files and folders must be selected in the Files and folders data source.

  Only non-system files or folders can be deselected. In case of deselecting system files or folders, the recovered system might be broken or non-bootable because during recovery process, only backed up files and folders are recovered.

Hardware requirements

If a source device is non-bootable or broken, it is necessary to have a separate device which is used to install the Backup Manager in restore-only mode and restore the rescue ISO image for the source device.

At least 2GB of RAM on the target device is required to load the ISO rescue image. Some Linux systems might require up to 8GB of RAM.

If the recovery system is frozen at boot time and the target device is a virtual one, try to increase the amount of RAM for this device.

Dissimilar hardware

Recovery to dissimilar hardware is possible but might require including additional drivers to the rescue ISO image. The disk layout and capacities must be the same as on the source device or exceed.

During Linux system state recovery, you can use target disks with bigger capacities than source disks.
