I have a laptop I want to keep regularly backed up. I have external hard drives that I use to do this, one that I carry with me and one that stays in my office in Portland. I use cloning software to duplicate the contents of the laptop onto them.
But I also want to do incremental backups, Dropbox-style, to a server I own.
I do have a paid Dropbox account and I do use it. (I also have a paid Microsoft OneDrive account.) But I'd really prefer to keep my files on my own server. What I want is very simple: the file and directory structure on the laptop to be mirrored automatically on my server, like such:
This should not be difficult. There is software that should be able to do this.
What I have tried:
Owncloud. They no longer support Mac OS X. Apparently they ran into problems supporting Unicode filenames and never solved it, so their solution was to drop OS X support.
BitTorrent Sync. This program is laughably bad. It works fine, if you're only syncing a handful of files. I want to protect about 216,000 files, totaling a bit over 23 GB in size. BT Sync is strictly amateur-hour; it chokes at about 100,000 files and sits there indexing forever. I've looked at the BT Sync forums; they're filled with people who have the same complaint. It's not ready for prime time.
Crashplan. Crashplan encrypts all files and stores them in a proprietary format; it does not replicate the file and folder structure of the client on the server. I'm using it now but I don't like that.
rsync. It's slow and has a lot of problems with hundreds of thousands of files. The server is also on a dynamic IP address, and rsync has no way to resolve the address of the server when it changes.
Time Machine Server. Like CrashPlan, it keeps data in a proprietary format; it doesn't simply replicate the existing file/folder structure, which is all I want. Like rsync, it has no way to cope with changes to the server's IP address.
So you tell me, O Internets. What am I missing? What exists out there that will do what I want?
