Backup every n minutes feature should retain them in a rolling manner

[camerons.web@…]

I would like lyx to retain the automated backups that it makes. In the config
you can set it to backup every "n" minutes (normally 5), and you can set
"Maximum last files" (normally 16, I think). That could be used to set how many
backups to keep. In $LYXHOME/backups or somewhere, the last 16 copies of the 5
minute autosaved copies could be kept. This would allow you to recover from
mistakes made up to 4 hours ago. That would be sweet.

Lyx files are small. This wouldn't take up much room, and the hooks for the
system are already there for the #filename.lyx# backups. Also, a gui for
recovery would not be needed immediately, as the backup files would be standard
lyx files.

sounds reasonable

I do not think we should implement this. The result could be achieved through external means (e.g. Dropbox's rollback feature or an external script that copies LyX's backup file).

Does any other software similar to LyX offer this feature?

I agree with wontfix.

There are specialised software for backups and for versioning; moreover Maximum last files has nothing to do with backups (as of now, but I doubt it changed meaning).
