In case you are using an old version of the software up to 8.6, please, rely on the second instruction. For configurations built on more drives (up to 8), UFS Explorer Professional Recovery can be employed. It can also be accomplished with the help of the Network RAID Edition of UFS Explorer. The procedure is illustrated here on the example of UFS Explorer RAID Recovery, which supports BeyondRAID on up to 5 drives. To restore data lost from Drobo under such circumstances, one can use UFS Explorer and the following instruction. Still, like any RAID set, BeyondRAID is not able to protect its data in the event of any logical issue, like mistaken deletion of files, software crash or incorrect rebuild. The configuration of traditional RAID is set up manually while Drobo chooses the needed algorithm itself, on the basis of the requirements of data availability at the particular moment, which will allow the array to withstand the physical failure of up two drives. Though such a system relies on data protection techniques similar to the traditional RAID, it significantly differs from any of the standard RAID levels. Data recovery from Drobo, DAS and SAN involves specific methodology due to the fact that such devices employ the proprietary BeyondRAID technology.
