Mac Time Machine - Can't Access Backup

Question

Successfully connected Canvio Home and installed all software.  I have run several Time Machine Back-Ups.  When I look in Finder I see the Canvio, can navigate to other folders on the Canvio, can copy files to/from the Canvio from Finder, but cannot access or view the folder where the Time Machine backup should be (CLNAS-BACKUP, where CLNAS is what I renamed the Canvio to).
When I try to connect to CLNAS-BACKUP I get a "connection failed" message.  But when I try to click on the "Connect As" button to connect as a different user - the login dialog box does not display.  I am able to disconnect and reconnect to the public folders on the drive. and I've tried ejecting and reconnecting to the drive - no change.
Not sure if this is a Mavericks issue or a Toshiba issue.  Really hoping for the former, as I have tried three other network drives and none have successfully completed a back-up - Toshiba was the first.  But not much use if I can't access the backup
Set-up:
> Canvio Home 3TG
> iMac Intel Core i7 | 16GB RAM running OS X (10.9.4)

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If all you see are messages that contain the word "Starting," you didn't clear the search box.
If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
