here is a tip:
I have been struggling with creating a backup and then “sending” it somewhere safe.
I tried mounting a thumbdrive, I looked into Amazon S3 cloud storage, I tried Filezilla and an FTP server. I got roadblocks with emailing.
In the end, all I really wanted was a copy of the backup file.
login using the remote GUI
backup locally (on your HD of the server)
then click restore. click the file, and you have the option to download the file! voila!! sorry had to share this revelation. I have been trying to get a copy on a thumbdrive forever. (yes, I am not a linux whiz)
