I recently installed Duplicati so that I could backup disk images created by another software package to Google Drive. The software I use to create the disk images takes cares of any file versioning. It makes a full backup every 90 days, and incremental backups every day in between. Given the large amount of data involved, what I need Duplicati to do is just upload any new files created and not do a full upload every day of all the files in the folder.
For example, on day 1 the backup software creates a full disk image, then I would like Duplicati to backup the entire image. On day 2, the backup software creates an incremental image, so the the local folder contains 2 files, the full image from day 1 and the incremental image from day. I would like Duplicati to only backup the incremental image from day 2, since the full disk image from day 1 is already on the cloud storage backup.
How do I set it up to do so?
Appreciate the help.
