Question
Adding an ssh or SFTP user for Vaultpress

Asked by jeffrey6f729b2968bb9ab9eaf
I need to add a new user so wordpress Vaultpress can connect for backups. Thing is it needs read-write access.
Steps so far:
useradd vaultpressr passwd vaultpress usermod -m -d /path/to/website/public vaultpress
usermod -G www-data vaultpress
So now I have a user named vaultpress, who is part of the www-data group, who can SFTP in directly to the directory I need vaultpress to back up.
Except vaultpress can’t write to the directory. Vaultpress needs write ability to put files back.
I frankly don’t know what rights the various groups have, I was hoping that being part of the www-data group would give vaultpress the correct rights.
What to do next.
Thanks!

Unless their setup has changed recently, you shouldn’t need to create a separate user. The plugin runs as the user and group that currently owns your files and directories – if that’s
www-data, then that’s who the plugin will run as and who the plugin will use to restore files if required.If you specify another user and files and directories are restored as that user and group, you may run in to issues and have to reset the ownership back to
www-datain the event you do need to restore.By default, files are generally
chmod644 and directorieschmod755.In the the case of writing files to a directory, a
chmodof 755 only provides write permissions to the owner, not the group or other. So even though yourvaultpressuser is a member ofwww-data, the group, they are not the owner.In the case of files, 644 only provides read and write to the owner, while only providing read to the group and other. So, much like with directories, if
vaultpresstries to write to a file, it wont be able to.…
If your files and directories are owned by
www-data:www-data, then that’s what the plugin would and should use.
