Does File Recovery plugin use lot of storage ? Is "every 5 mn" for "10 years" reasonable ? How to backup snapshots?

Help

  1. If I don’t modify a note, will it consume storage every 5 mn ?
  2. If I edit a few lines of text (from ~1 to ~50 lines) for ~1h to ~5h on ~1 to ~5 notes daily : is saving snapshots every 5mn and up to 10 years reasonable ? How much data would that consume on my disk ? Let’s say 30kb for an edit, so that would be 0.030Mb x 5h * 12 (number of edits / h / note / day) * 5 notes * 365 days * 10 years = 32850Mb, right ?
  3. What folder should I save in order to backup my File Recovery snapshots ?

Thank you !

Our valued member, @ush decided to not reveal his answer but I reckon it would have been something like this:
Use the File Recovery plugin for short-term or temporary use only and create backups manually of your vault with a non-Obsidian method.

I use git so I don’t use this Obsidian File Recovery that much, but I seem to remember the default setting (every 5 mins for 7 days) is roughly a good starting point. I’d go for 2 mins for 14 days max, or something like that.
10 years is unreasonable, at least in Obsidian core plugin terms. Especially because of storage locations; help docs relate to snapshot storage as well (actual path is unknown to me):

In another post you mentioned git, so I reckon you are safe with that alone too.

Snapshots are only taken when the file changes.

I think they’re stored somewhere in the Global Settings folder. How Obsidian stores data - Obsidian Help
