Backing up/migrating a very large multisite with Snapshot

I ran through the backup process with the Snapshot plugin, and it seemed to have worked. When I went to download the backup, the file was 0kb. I'm wondering if this has to do with the size of the multisite. Is there a limit to what this plugin can back up?

    Hi there, ImagineDesign!

    There's no inherent limit within Snapshot itself, but you may be limited by your server resources. Backing up an entire multisite, especially a very large one, is going to be very resource intensive. I would suspect that your install ran out of resources while creating the Snapshot, which is why your completed backup was empty.

    Can you check your server error logs from around the time the Snapshot was being created and see if there's anything of note in there? Most hosts will let you access your error logs via your hosting control panel.

    Thanks, ImagineDesign!
