    1 backup is no backups.

    Backups in one location is no backups.

    A backup not tested is no backups.

    A backup that automatically mirrors changes without storing history (RAID or other mirrored filesystems are example of systems that fail to do this) is no backups.

    Data not backedup does not exist.

      RAID doesn't do anything for storing history. RAID can be part of your backup strategy (mainly uptime) but RAID is not a backup.

        which is exactly what I was trying to say. my sentence was ambiguous though. I meant that RAID and mirrored filesystems were examples of 'A backup that automatically mirrors changes without storing history'. Ive had too many clients call raid a backup. It is not. Edited my post.

          Yeah, the way I'd phrase it RAID is intended for reliability (or as the 〈R〉 in RAID stands for redundancy), but not for recovery. Having reliable storage is good, but a separate concern from recovery backups (and reliability of the backup storage is good too).

            Yup. my server has a RAID1 so that it doesnt go down due to wear, and daily backups to tarsnap for more unexpected things happening. I think RAID is good for routine failures (hardware wear, mostly), but not much else.

            But that doesnt fit into a trite little poem very well.

    This is quite timely for me. I started looking into seriously backing up my family’s computers after I saw an ad on LTT for acronis. I tried a few, and still haven’t bought anything, but I think I am going to buy the Arq backup family plan and get all my family backing up to their own OneDrive accounts. I may also include a less frequent backup to my synology, but their upload speed is pretty trash already, so those may just take forever.

      I've been using Acronis for about 8 years now and haven't had any issues, but I think they're moving to a subscription model (because of course they are). Macrium Reflect and Veeam might be of use.
