"This term is used in the 1-Touch recovery of Windows clients. When the disk configuration of the restored system is different than that of the backed up system, you need to perform a Dissimilar Disk Restore."
Thanks but my one question i am stuck on is, i was advised if the destination client had the same size or larger drives and same amount of drives, it was recommended by Commvault engineer that you could use the similar disk restore. They just couldn’t be smaller drives. Is that accurate.? Thanks for the help
