Amidst the storage system failure, worlds corrupted?

Hello there. I understand there have been some major issues regarding aternos servers over the past few hours. From what I can gather, lots of people have found there world lost, including me. Luckily I have some automatic backups, and normal backups. However, I tried to load in the most recent backup from 1:13AM today, just to find modded blocks not rendered in (no mod creative item list either), and then I look behind me, a huge amount of chunks of previously built-on land has been reset to a new random jungle biome, suggesting the world file is now corrupted.
My queries are as follows:
Is this particular backup corrupted because it is backed up within the time frame of the failure?
If that ^^^ is so, would backups I have from say, 3 days ago, work properly, if I loaded it in, or from the system storage failure, would they also be corrupt?
And, if not, is there any way I can obtain these "potentially" safer world backup files, so I can possess them on my own system?

Thank you for any help given, as I would hate to loose a world I have spent over 2 years building block by block.

Chazi.

Why thank you Roman! Honestly I don't know why I don't try stuff like this! It has managed to load up fine and whole this time! Thank you for your words of wisdom
