It's one of two backups. The software is great. Dropbox level of just works. iDrive by comparison is cheaper but always errors and files it couldn't touch.
"Yeah do NOT do iDrive if you use git or care about symlinks, I learned the hard way. Backblaze doesn't backup symlinks either for that matter..."
Gosh, if only there were a cloud storage provider that gave you an empty UNIX filesystem you could do anything you wanted with ... maybe something built totally on open standards that could handle hardlinks and symlinks and such ?
