The EVO shared storage systems allow for several possible RAID levels, and even multiple RAID levels per pool, but while RAID provides a level of protection against a hardware failure, it is not a substitute for backing up data.
Although RAID can offer some protection against data loss due to disk failure, RAID is not a backup strategy. All critical data contained on any storage device should be routinely backed up to at least one other device, and a set of your backup data should be securely maintained at a separate physical location.
Any backup utility that’s capable of mounting network shares can be used to mount EVO volumes and copy their data to the backup destination.
EVO Nearline is an affordable storage solution specifically designed and built to act as a stage between the online storage and backup or archive.
We also partner with StorageDNA to make the archive process simple, and we continually develop more backup/archive integration to both EVO and the ShareBrowser software (follow us on Twitter for news about these developments).
Finally, while our Slingshot utility is not currently designed to completely replace your backup solution, it does provide powerful automation options, including the ability to move data to directly to Amazon S3/Glacier. Let us know if you’re interested in becoming a beta candidate!
