Hi All
I did a search for this and could not find anything but I have just had an issue with my Yubikey requring me to backup and delete my Bitwarden account as the recover key was not being accepted. What I think you should do is inside the bitwarden desktop client rather then just have the export function also include a backup location for the JSON file so that you can configure a backup of this to run to a schedule or every time you open the application.
My desktop is then backed up to crashplan small business and I often configure auto backups of key items on schedule so that its doing this automatically.
Password safe falls into this category and would not be that hard to include in your clients ?
Thanks
Matt
