I have Time Capsule for my Time Machine backups. It always works flawlessly for years. I cannot remember how long I had it but I know I got it after it was discontinued (last stock remaining before it gone forever). Anyway every since I updated Mac OS in September I keep getting this message, screenshot below.

I have keep doing "Erase Backup History" every time and it works for bit like 2-3 weeks then this pop up again, repeat and again, repeat and again. Does this mean my Time Capsule hard drive is failing?
I did used to do Time Machine backup with my previous NAS and it was nightmare and always failing so which why I got Time Capsule and it been brilliant until September this year 2024.
If it is failing then looks like I need get external hard drive attached to Mac 100% of time cos none of NAS works well with Time Machine except Apple own products.
BTW I am using Mac Studio M1 on Sequoia on latest version.
