Every save triggers 4 consecutive saving processes #27

Hi
If I save the database, instead of 1 second it takes four times the amount as the process bar goes from 0% to 100% four times instead of one. That's quite annoying. I could lower the number of key transformation iterations as a workaround, but still I want to know why it does that.

The KPSimpleBackup plugin used the built-in "save-feature" of KeePass for databases. If you've enabled Long-Term-Backups, KeePass has to save your database four times. Thats why you see the progress bar four times, which is - even though it might be annoying - expected behaviour. I don't know of any way to overwrite the progress-bar indicator to only go once from 0 to 100 % while KeePass is saving the Database four times :/

Hmm, I didn't expect the L-T-B to resave e.g. the yearly backup on every little change. Personally I don't even expect the long time stuff to be up to date. A monthly backup should contain the last status of the past month, not the current month. I don't need a yearly backup from 2020 because 2020 is not over yet and I have loads of more recent backups.

You get the point? So the saving strategy imho might need an overhaul. Nonetheless, great plugin!

/edit Because it is annoying, people might lower their key transformation iterations which lowers crypto security.

The concept of ltb backups is to provide a latest yearly, monthly and weekly version. So I actually want to have the latest version of 2020 in my ltb yearly folder (so that it is the latest 2020 version, if 2020 is over).
But I also actually have an idea, how to speed up the saving process, if ltb is enabled (I'll open a new issue for that).
I additionally will check, whether it's possible to trigger the ltb backup only, if KeePass and/ or the database get's closed, which would not lead to multiple saving-events, unless the application is closed.

FYI, here are the new issues:

Btw, as a workaround in the meantime, you can disable backups on every save and enable them on closing (second option under Advanced Backup Options). This will stop backups up on every save but only, if the Database gets closed.
