I have a 56 TB local Unraid NAS that is parity protected against single drive failure, and while I think a single drive failing and being parity recovered covers data loss 95% of the time, I’m always concerned about two drives failing or a site-/system-wide disaster that takes out the whole NAS.
For other larger local hosters who are smarter and more prepared, what do you do? Do you sync it off site? How do you deal with cost and bandwidth needs if so? What other backup strategies do you use?
(Sorry if this standard scenario has been discussed - searching didn’t turn up anything.)
I can’t remember the name of an excel spreadsheet I created years ago, which has continually matured with lots of changes. I often have to search for it of the many I have for different purposes.
Trusting your memory is a naive, amateur approach.
If the spreadsheet is important it sounds like it would be part of the 4 GB that was backed up.
Psst, you missed the point and need to re-read the thread.
The key here being that you actually remember the file exists, because it’s important. Some other random spreadsheet you don’t even remember exists because you haven’t needed it since forever is probably not all that important to backup.
If you loose something without ever realizing you lost it, it was not important so there would be no reason to make a backup.
You put that with everything else similar into a folder, which is backed up. Mine is called “Files”. If there’s something in there that I don’t need backed up. It still gets backed up. If there’s something very large in there that I don’t need backed up, it gets removed in one of my “oh shit these backups are huge” purges.
So you do remember that you have several frequently-used spreadsheets.
