Problem with Yosemite?

data is obviously important. So I should look to replace all the discs? And just do a hot swap one by one starting with Disc 1? I find it odd this happened just as I upgraded to Yosemite. Maybe just a coincidence?

Likely a coincidence. Well replace disk 1 then if it icomes up O.K. (apart from e.g. TM not working) backup your data, then if that works try a reboot with a quota check.

Well the drive works fine, yesterday I uploaded some FLAC music files and listened to other files, no problem.

So still replace disc 1, back up data to an external HD, then try the reboot with quota check and see if time machine comes back up?

Sorry for asking so many questions, just want to make sure I do the process correctly.

Also I was looking for a HCL for external drives, found a mish mash of links. Somewhere I read 2 TB external is the largest it can support?

I have more than 2 TB of data, how would I back it all up to an external HD? Can someone provide some insight? I was thinking about getting the WD My Book 4 TB. Will that work?

I'll post in the USB Storage area as well.

The easiest and fastest way is to connect the USB drive to a PC and back it up over the network. That gives better performance, and eliminates compatibility issues.

ah ok, so if I hook up the new WD 4 TB my book to my PC as an external drive, then just back up over the network? Surprised that gets better performance over the network vs USB direct, but I'll trust you. I can see how it minimizes compatibility issues though and that is a good thing in this case.

In this set up can I set up auto backups of the NAS to the hard drive? Assuming the computer is on so the drive is on? I could also get a USB > Ethernet hub and put it on the network? I have open Ethernet ports in a switch in the office, but no router with a USB port to put a USB device on the network.

I'll get a new supported HD, replace disc 1, let it all re-sync, then do the backup to the external drive, then do the other steps mentioned. Anything else please let me know.

Thank you

Performance on a gigabit network is almost 10x faster than direct USB backup on the NV+ (USB backup using NTFS format is about 3 MB/s on the NV+, you can get ~20 MB/s over a gigabit network).

If the PC is on and the USB drive is shared you can schedule backups with frontview.

Another approach is to use a PC backup program to pull the data from the NAS. My backups to PC drives use robocopy scripts on the PC, which are scheduled. I schedule them by adding them as a postprocess to the acronis backup jobs already running on the PC.

My setup is Windows of course, but a similar approach with Mac should also work.

I got a new drive (one that is supported). But it in, got the notice that the sync is all done, everything looks fine. Go to turn on time machine, still nothing. Time Machine will not even recognize the drive. The options are two SD Cards that are in an SD card reader, a CD that is in the CD Drive or "other airport time capsule". No NAS option.

Did you try the reboot with quota check?

Can you send me a fresh set of logs?

ah forgot that step, sorry. do that first, or send you the logs first?
