Also I don't see why the encryption on budget backup tools is going to be any better than that on ZIP files, which turned out to be extremely vulnerable to plaintext attack. the possibility of you being denied access to your files at a critical moment. There's a trade off between the risk of the backup falling into the wrong hands vs. The downside is it is hard to get 'depth', a mirror backup only holds the latest version so it doesn't protect against files being changed or deleted.ĭata recovery 'fire drills' should be considered.Īlso think carefully before encrypting your backup copies. One nice thing about mirroring to another NAS is you can actually 'see' the backup copy as a windows drive. Your Mac sees the RAID array as a single volume, allowing any backup programme, such Intego Personal Backup, to copy data from those drives to other drives.Īnother really important point about backups is to make sure the right things are being backed up, and that you are able to recover successfully. This may be, for instance, two ordinary 8 TB drives, with a backup of a portion of the RAID array's total storage to each drive.

You should back it up to another device if, for example, your RAID array has 12 TB of storage. You must still back up your primary disc even if it is part of a RAID array.

RAID arrays can improve data safety, but the extra discs they contain shouldn't be viewed as backups. One of the key goals of data integrity programmes, which are also used to uphold data security, data quality, and regulatory compliance, is to ensure data reliability.
