Data recovery from redundant complex data storages
With increasing popularity of devices with high storage capacity, RAID-based systems have become common both in large companies and at home workplaces. Most complex data storage systems ensure high data safety by means of redundant writing, yet, even these systems do not guarantee a complete protection from formatting, malfunctions or accidental deletion of valuable data.
The chances for successful data recovery from RAID depend on the method of data protection (mirroring for RAID level 1; parity for RAID levels 3, 4, 5 and 7; Reed-Solomon code for RAID level 6).
Data recovery from RAID is a task for storage-specific data recovery software. SysDev Laboratories offers UFS Explorer RAID Recovery for simple RAID-related tasks and UFS Explorer Professional Recovery for more complicated cases.
These software utilities allow
assembling RAID virtually;
imitating data distribution algorithm applied by the controller of the given array;
reading information on the file system as it is.
If the components of these virtually assembled arrays fail, UFS Explorer enables data recovery using redundant information.
Note: If more than one component fails in RAID4 or RAID5, data recovery is possible only after the components are repaired. It's recommended not to conduct this procedure on one’s own and rather take the device to a specialized service center.
