Question about duplicacy and onedrive personal

Etienne     May 29 4:50AM 2017 CLI

Hello,

I used to use rclone together with an Amazon Cloud Drive account... With the recent ban of rclone by amazon, I'm force de rethink my backup procedure.

I finally decided on a yearly subscription to office 365 family.

My household can use Microsoft OfficeSuite and I have potentialy 5x1TB of storage...

Duplicacy seems to be the tool of choice for backuping my NAS

Now my questions:

  • I looked into the storage written on Onedrive and noticed that the chunk directory contains ALL the chunks... How will behave Onedrive with a very number of chunks in one directory .. Wouldn't be worth implementing a one or two level of directories ( using the first 2 letters of of the hash) to somehow limit the number of files in one directory ??

  • I've seen in the doc that it's possible to attach multiple storages to one repository. Does ducplicacy spread the data on the multiple storages ? Let's say I have a directory on my nNAS ( Photos/Videos) being bigger than 1TB ( current limit on Onedrive). will I be able to backup it using duplicacy if I define 2 storages using 2 of my 5 onedrive family accounts ?

Thanks in advance and looking forward to your answers ;-)

Regards Etienne

We implemented a hierarchical directory structure for storages that more resemble a traditional file system (like SFTP and Dropbox) but treated all others as an object-based storage so the chunk directory is flat for those. There doesn't seem to be a hard limit on the number of files per directory for OneDrive. Of course, this would become a problem if you sync the storage directory to your own folder but I doubt that you'll ever need to do this.

Yes, it is possible to attach additional storages to one repository but that is for backing up the same repository to multiple destinations or copying backups from one storage to another. It can't be used to split one backup into different storages. For that you'll need to initialize separate repositories for different directories.

Edit: it can be used -> it can't be used

Thanks a lot for the useful answers !

Time to get our hands dirty and set-up backup procedure using duplicacy !!
