DuraCloud Synchronization
...
- Does DuraCloud automatically synchronize all changes in the local folder? For instance, if a file is deleted, is it removed from the cloud storage?
- Tim's Answer I talked to Bill Branan from DuraCloud team. The current implementation of the Sync Tool always synchronizes with local folder contents. So, if you delete a file from that folder, it will be removed from the cloud storage. However, after our discussions of use cases, Bill agreed it may be necessary to have a way to "turn off" the auto-delete functionality. So, that if you remove a file locally, it will not auto-delete it from the cloud (unless you explicitly force the delete).
- Would it be possible to perform a "trickle" synchronization for large amounts of content? For example, if your DSpace has 1TB of content, you wouldn't want to export the entire 1TB at once locally (thus doubling your local storage needs). Rather, maybe it would be possible to export 10GB at a time to a local DuraCloud Sync Folder, and have that content "trickle" up into the cloud.
- Tim's Answer Again, based on discussion with Bill Branan. Currently, the DuraCloud Sync Tool doesn't support this sort of "trickle" synchronization. However, it could support it if there was a way to turn off "auto-delete" in the Sync Tool (so that it would no longer auto-delete content in cloud which has been removed from the local sync folder).
Possibility: Adding an option to turn off "auto-delete" in DuraCloud Sync Tool?
In the end, it sounds like our best option may be to ask the DuraCloud Team to create a way to turn off the "auto-delete" option of the DuraCloud Sync Tool. Bill Branan seemed open to this idea.
