I think I don't get how Duplicacy works

Hi guys,

I recently installed duplicacy in order to backup some important folders on Gdrive. So I followed the guide and successfully created a storage gcd://StorageFolder and a backup of my directory C:\BackupFolder.

Now what I excepted o find in StorageFolder in Gdrive is a copy of my directory BackupFolder or at least its content. So either I don’t understand how backup should work or my setup is not working.

What do you think ?

Thanks guys

It sounds like what you thought you were getting was synchronization, where BackupFolder is copied verbatim to a corresponding folder on GDrive. That’s useful for some things but isn’t a good strategy for backup. If you synchronize the folder on Monday, delete a file on Tuesday, synchronize again on Wednesday and decide on Thursday that the file you deleted was important and you need it back, it will be gone from the backup copy with no way to recover it.

Duplicacy (and other backup software) stores the files and information about them so you can go back to any point in time where you have a backup and recover from a loss. In the scenario outlined above, Wednesday’s backup wouldn’t have the file in it (because it was gone by then), but Monday’s would and you could restore from that. What you found in your GDrive folder is Duplicacy’s way of doing that. I’ll spare you the technical details and say that what Gilbert has done with it (a) is very clever and (b) works very well.

Thanks for the response. It was maybe a bit naive but I though it would work somehow like github, with a kind of synchronized copy with versioning. I’ll trust Duplicacy on how it backup data and go with it :slight_smile:
