Before you start using disk imaging, first read this entire section of the User’s Guide. Please take several precautions including backing up the system that you will be testing the LinMin Server’s imaging function with. Disk imaging backup is a non-destructive process, however disk imaging restore will erase and overwrite all contents of the system you are restoring. Before doing a restore, please look at the directory where the image files are stored to ensure that what you see in that directory is reasonable, allowing for compression. E.g., if you back up a system with 250 GB of data on its disk(s), and the backup directory contains only 10 MB, then clearly something wrong happened during backup (you should expect a 3:1 compression ratio on average.)

 

You can also monitor progress on the client system’s display, along with progress bars, average backup/restore speed, elapsed time and estimated time to completion.

 

Please become familiar with the disk imaging subsystem before restoring a mission critical system.

 

Before you create an imaging profile, you will need to know the client machine's:

•MAC address.  You must know the MAC address for each system you need to image.
•You must also know the drive where the master boot record (MBR) is located, e.g., sda, sdb, sdc (for SATA drives), hda, hdb, hdc and so on (for IDE drives). If using Linux, use the df command to identify your disk type. Most systems in use today use SATA drives, so try "sda" first.
