I think it would be interesting if you add the automatic backup feature.
For example the user can select an (or multiple) email and bitwarden could email a .7z (or kdbx) file containing his passwords.
For example the user can select an email and bitwarden could email a .7z (or kdbx) file containing his passwords. It stands to reason that the .7z file would be encrypted using the vault password.
In this case, it would be possible for the user to configure how often bitwarden should send him an email containing the password backup
I also think it would be interesting for bitwarden applications to download all data from the vault in formats (.7zip , .zip or .kdbx), in which case not only the passwords and notes would be present but the files saved inside the vault as well .
See, the export function is really great, but I personally see some problems with it. For example the .json file can only be imported again within another Bitwarden account. And the .cvs, which is the most compatible file format with other password managers, is not encrypted.
Another problem is that when you export your vault, you only create a backup of your passwords, which is somewhat inconvenient since Bitwarden, when pressed, offers the option to store files inside the vault as well. So I think the suggested formats would be good options as they can store both passwords and files within them.
For those of us who are tech savvy, creating a backup manually is a lot. And save it anywhere, but for older people who are not so tech savvy it would become a very big challenge, so for them it would be almost impossible for them to backup their vaults frequently. For this reason, I initially suggested the idea of sending files by email so that they would always have a copy of their backups saved as an email attachment.
The idea of putting multiple e-mails as recipients of your vault is so that if you ever get locked out of your vault and your accounts, you can recover your bank of passwords simply by asking your friend who received a copy of your vault in his email. of course the copy would be the encrypted version of your vault.
