Is there a tool that I can use on Linux to make a backup on the cloud for a list of files and folders so that only changes made to each individual file is uploaded to the cloud, without having to store duplicates locally. I think DropBox have something like that bu just for one folder, so I think I would need to have duplicates of each single file and folder in the list in the DropBox folder, and keep then in sync, which is what I'm trying to avoid.

I use Duply (simple Duplicity) for my Linux server backups because:

  • it is incremental
  • the backup is encrypted
  • it is simpler than Duplicity

As mentioned here, it can be configured on Ubuntu to backup to DropBox (I never tried myself).

Here is a list of protocols mentioned as theoretically supported on the duplicity page:

  • Amazon S3
  • Backblaze B2
  • DropBox
  • ftp
  • GIO
  • Google Docs
  • Google Drive
  • HSI
  • Hubic
  • IMAP
  • local filesystem
  • Mega.co
  • Microsoft Azure
  • Microsoft Onedrive
  • par2
  • Rackspace Cloudfiles
  • rclone
  • rsync
  • Skylabel
  • ssh/scp
  • SwiftStack
  • Tahoe-LAFS
  • WebDAV

Also, I give Duply the list of folders to backup without ever having to duplicate those folders.

Finally, I never tried to backup a single file but this page mentions that single files can be configured to be backed up with Duply:

Duply normally uses a whitelist. To include certain directories or files from a backup the exclude file must be created in the Duply directory. The syntax allows you to add directories and files using + /pfad/zur/datei. To exclude a directory the exclude ein - /pfad/zum/Verzeichnis command must be inserted. In addition, Duply allows the use of wild cards. The file illustrated here exclude secures the directory /etc/, /root/, /var/www/ and excludes all other directories.

  • /etc/
  • /root/
  • /var/www/
  • **
