SimpleDatabseBackup is a KeePass plugin which was created for simpleness. There is no setup, no GUI and no configuration. Just install and go. That's all.
It will create a backup for every opened KeePass database (.kdbx) every time a database with changes is being saved. The backups will be placed in the databases source folder, with a maximum of 5 backups. The backups will be rotated, newest in, oldest out. SimpleDatabaseBackup is fully cross-platform compatible.
NOTE: SimpleDatabaseBackup currently creates local backups only. Since most users having their database in some sort of local-to-cloud syncfolder that's ok because the backups are being synced by the cloud application. Remote databases (sftp, scp, ftps) are not supported currently. I'm working on this but this is more complicated and I've to do this on my spare time. Please be patient in this point...
The compiled plugin can be downloaded here:
https://github.com/jnko/SimpleDatabaseBackup/raw/master/SimpleDatabaseBackup.plgx
Please follow the KeePass documentation: https://keepass.info/help/v2/plugins.html
In short: Just put it into the KeePass.exe folder.
To update quit KeePass and overwrite the older release. That's all. After updating the plugin please always manually remove the backup databases.
At the time of writing this the number of backups is hard-coded into the sources, but you may follow the excellent documentation on the KeePass website and build your own customized plugin or you can create an issue here and if there is some need from the users I will add this freature request.
This plugin is heavily based on the DatabaseBackup plugin written by Francis Noël which you can find here:
https://keepass.info/plugins.html#databasebackup
There is no license or copyright information left in the original sources so I hope Franics allows me to re-use parts of his code. If not, please leave me a note.
I created this small plugin because I use KeePass daily with one personal and one shared business database. Even not enough on I need to do this on cross-platform operating systems every day. People tend to make mistakes from time to time. That is the right moment for backups.
At the time I only used Windows with Francis DatabaseBackup plugin everything was fine, but since I need to switch between Windows, macOS and Linux I realized that Francis plugin doesn't play nicely. It has some serious bugs when using multiple databases and the path names were not cross-platform compatible. So I forked DatabaseBackup, removed the GUI, stripped out everything unneeded and modified it for my needs - cross-platform, simple, silent ==> SimpleDatabaseBackup
