Backups and storage questions.

[Ronin.badger]

Hi all! 

 

So for sometime I have been using a raid 5 or equivalent array in my PC as a main storage with a single external backup. 

 

Yes, yes, Raid is not a backup, but what about backup parity.  For my "off site" backup would it be advisable to create a parity array with my external "local" backup. Putting one disk in a safe or deposit box. 

 

My thinking here is: it will be backed up in intervals, not beholden to any corporation (less hands able to touch, lose, access it), and with the parity it will resistant to random bit rot between intervals. I can also have 3 drives in parity so the drive in transit replaces the drive in storage. 

 

My data is backed up locally in a Nas like config on my PC. Then detached backup. And a parity instead of a clone "offsite". Would the parity setup be a good idea? It would be a backup drive with error checking.

I don't like having things on the cloud either, and really there is stuff I just don't want on the cloud.

 

This is how I work my backups:

 

- Pretty much all my PCs have two drives in them, that data is mirror across.

- This data is backed up to the other PCs in the house.

- All that data is backed up to my NAS.

- I have multiple pelican cases that I keep pairs of external drives in. (Pairs so a single drive failure doesn't matter) These have the important data backed up to them.  So I have some in safe, and one at all times off-site. Then every so often, I take one with me, and rotate it with my off-site one so I can update those drives.

 

It's similar to how you are working yours, but I'm using more external drives.

Not sure I follow..

You want to have ONLY the parity drive backed up off site? Or do you mean a whole second array offsite?

To clear this up. 

 

I have one array  I My PC. Raid 5. 

1 external backup drive. 

 

Want to mirror my back up drive for off site or safe storage. No striping on the backup.  Similar to OhioYJ but w/o a NAS.
