My Linux root server’s hosting price plan includes a 50 GB backup storage option. The backup server can only be reached using FTP, unsecured. Even though the backup server is only visible from within my server provider’s local network, I still don’t want to expose all my server settings, accounts and databases in clear text to a man in the middle. Or, I don’t want an untrustworthy subject with access to the backup server’s file system to be able to read my backup. Also, I don’t want to send my entire site to the backup storage every day as this would eat up my 50 GB within days.
This is where Duply (formerly known as FTPlicity) comes in handy. Duply claims to make your incremental encrypted backups on non-trusted spaces a child’s play. It manages backup job settings in profiles and allows to batch execute commands. It supports symmetric and asymmetric encryption using GPG.
Duply is not limited to FTP, you can also send your backups to a IMAP, WebDAV or ssh destination (and even more!). I haven’t tried the IMAP method but in theory you could send your encrypted backup to a free Google mail account as long as you don’t exceed the 7 GB provided by Gmail. However, in this sample, I’m using a FTP scenario with asymmetric encryption.
