Backup Database on successful load

[Onering20]

Is your feature request related to a problem? Please describe. I had my data base corrupt after messing with attachments (assuming this was the issue based on other posts). Last proper backup is over a month old.

Describe the solution you'd like On a successful load of database it writes/overwrites a file of the same name &.bak or similar as a copy in the same folder or in a app folder. Changes made to the database during the following session are not made to the backup

On a failed load (database corrupt) offer to restore from the backup (backup file is not removed by this operation

At worst lose one session of progress not a month

Describe alternatives you've considered A warning about attachments and possibly a copy of the database without the unstable elements

The backup system must be done externally, as explained in the wiki. https://github.com/Kunzisoft/KeePassDX/wiki/Backup It will be possible to configure the backups in FileSync and KeePassDX should remain a simple editor. https://github.com/Kunzisoft/FileSync

On the other hand, if you have a problem with the attachments, it should be identified, I haven't noticed any problem there. Can you upload a database and a procedure to reproduce your corruption problem?
