Copy & backup into the same storage?

#1

I am using Duplicacy CLI to backup files from various computers onto a storage on my local server. I then also want to create an off-site copy of that storage to a remote second server, so my thinking was that I could use duplicacy copy for that.

However, I also want to use the storage of that second server as an independent backup target for the first server (i.e. for files that only exist on my local server for example).

I am not sure if it’s a good idea or possible to duplicacy copy from one storage to another - but then also run duplicacy backup onto that latter storage as well? Or should it ideally just be separate storages.

I would do that, I think it’s not only possible but also advisable… Best case – it will deduplicate data from your server and client machine. Worst case – data is unique so it won’t. Note, you would use separate snapshotID for the data from your server.

You are not burning any bridges this way – if later you decide that you do want a separate storage for the server data for some reason (I’m not aware of any common reasons though) – you can always create it, do duplicacy copy of that server snapshot and continue backing up your server there, and then prune it from original storage. But again, I don’t see any downsides in keeping everything in one place, provided the filesystem on the target is robust enough to handle massive number of chunk files. Most modern filesystems don’t have any issues with hundreds of million of files, so it shall be fine
