Eugene's observations

For any who succumbed to Microsoft's tempting offer of using OneDrive (formerly SkyDrive) for online storage that can be linked and several devices, know that the rug is about to be pulled from your feet.  On 27th July the amount of free storage that comes with OneDrive will change from 15 GB to 5 GB. They are also discontinuing the 15 GB camera roll bonus.  More details on their website. 

This leaves Google Drive as the clear leader in the field as they continue to offer 15GB free space that can be shared with several devices.  

• This is very handy for sharing files that are too large for email attachments.  
• Also good for editing documents collaboratively and concurrently.  
• Good too for storing documents you want access to when away from your own devices - on holiday at a Greek taverna perhaps.
• Excellent as a repository for documents you want automated versioning backup for 30 days to supplement your regular backup and be part of your disaster recovery plan.
• Finally, this is a saviour for those who want to use File History to backup a few files when offline backup is not wanted.  Note though that a network drive has to be established to point to a location on the same disk that is being backed up.
