I've been using SugarSync as a cloud service provider for years. However, recently I've been becoming increasingly frustrated with their services. I've noticed that over time, their upload/download speeds have decreased, and recently there's been a few bugs that have been quite unforgivable (can't drag/drop upload files in Chrome; freezes whenever I view the "SugarSync Drive" folder, etc). My subscription expires in a few weeks, and instead of spending over $100+ to renew for another year, I'm looking to find an alternative cloud storage provider instead.
Two of the main features I'm looking for are the ability to sync multiple folders in different locations (as I have folders on different drives/partitions I want to sync), and file versioning (in case of accidental deletion, corruption, etc). Neither is something I'm able to be flexible on, or willing to use work-arounds on (such as folder junctions). I've been doing my research, but so far haven't had much luck:
* Dropbox - Only syncs one folder.
* Google Drive - Only syncs one folder.
* Skydrive - I'm not overly fond of their track record regarding privacy.
* Mega - No file versioning.
* Synology - Only syncs one folder.
I'm not against using a private/in-home cloud like Synology (in fact, kinda prefer that as they're one-time costs and the speeds would be much higher), but really I'm just looking for a good option that'll get me away from SugarSync's flaws.
