Time Machine restore failed

I am in a bad predicament. I have been storing Time Machine backups on my Synology NAS. Everything (I thought) was great except when I tried to restore from my time machine backups (the whole mac disk). The restore continues to fail with a message like "NSAlert is being used from a background thread, which is not safe. This is probably going to crash (sic) sometimes. Break on void _NSALertWarnUnsafefeBackgroundThreadUsage() to debug. This will be logged only once. This may break in the future." Restore failed with exit code -50.

So now I cannot restore from Time Machine backups (from my NAS) after the restore process wiped clean my Macbook pro hard drive.

I would love to be able to "browse" a backup "band" on my NAS to get my pictures and videos but when I try to open a "band" my NAS has no idea what kind of file it is nor does it know what to use to open it with.

Obviously I am a newbie to Time Machine (and this is my first macbook pro) but I am not amused. Currently running Yosemite although the mac came with Mavericks installed.

Please someone help!

Thank you,

Mark

MacBook Pro (Retina, 15-inch, Early 2013)

Non-Apple NAS devices are not compatible with Time Machine, regardless of their manufacturers' insistence otherwise. To learn how to use Time Machine please read Use Time Machine to back up or restore your Mac:

Time Machine is the built-in backup feature of OS X. To use it, you need one of these external storage solutions, sold separately:

External hard drive connected to a USB, FireWire, or Thunderbolt port on your Mac
Time Capsule or OS X Server on your network
External hard drive connected to the USB port of an AirPort Extreme (802.11ac) base station on your network

That is all.
