Frequently Asked Questions about Disk Image backup

Can I backup to local, network, NAS, external drive, or the cloud?

Can I run multiple backups (Disk Image and Files & Folders backups) on the same machine at the same time?


Yes, Comet supports running multiple backup jobs simultaneously, to the same or different storage locations.

Does Disk Imaging also work for Windows Servers?


Yes, the Disk Image backup will work on most newer versions of Windows Server. The minimum requirements are detailed here:

For USB recovery, can the image be downloaded from the server during the restore process?


Comet's USB Recovery option allows you to boot into a minimal Windows-like environment. Log-in to the user profile account, download the backed-up Disk Image from the storage location, and write it to the hard disks of the connected machine. This is a bare-metal type recovery.

Can I restore the full disk to an external drive for cloning?


Yes, however the destination device needs to be as large as the original. You can also restore as .VMDK file format, which allows mounting in many different virtual machine programs (VirtualBox, QEMu, and so forth).

Will a disk image restore work on systems that cannot physically be accessed?


As the backup administrator, when the target PC is online and running it is possible to remotely initiate a restore job from the admin web interface, by remote-controlling a live-connected Comet instance.

How does the pricing for the Disk Image booster work?


Files & Folders backup is Comet's base offering. After adding your protected devices, you can choose additional boosters, such as Disk Image. The cost of protecting a single device with disk image backup is $2 for Files & Folder backup + $3 for the Disk Image booster = $5/device per month (in USD)
