RSync W/ Windows- With SSH Keys & BQBackup

TLDR version:

when populating and attempting to write keys to authorized_keys I'm receiving the following error:

Quote:

Could not create directory '/home/Administrator/.ssh'

Long version:

I've been grinding my wheels with this for a long time now. Basically I'm attempting to get rsync set up to backup some data directories on my Windows 2k3 Server through a batch file with task scheduler to bqbackup. I've been back and forth with both Scott and Rsync.net's tech support about this issue - both of which have been great... but essentially keep hitting the same impasse with Scott appearing to have hung his hat stating he's not familiar enough with windows and rysnc.net telling me to wait for their GUI client that should be launching "soon." In the meantime I'm just running the backup manually until I can get this key issue figured out.

Here's what's going on:
I've been mainly using BQ's Guide and Rsync's Guide to try and accomplish this.

After executing ssh-keygen -t rsa -N ''

I receive the following message:

Quote:

Generating public/private rsa key pair.

Enter file in which to save the key (/home/Administrator/.ssh/id_rsa):

If I accept the default value it gives me I receive this error:

Quote:

Could not create directory '/home/Administrator/.ssh'.

Open /home/Administrator/.ssh/id_rsa failed: Not a directory.

Saving the key failed: /home/Administrator/.ssh/id_rsa.

Now my thoughts were this was occurring because my %homepath% is actually:

Quote:

c:documents and settingsadministrator.DOMAIN

(DOMAIN replacing actual text)

I'm able to change the default path location and create the RSA file elsewhere using the cygdrive format... so when prompted for the path to save I instead input:

Quote:

/cydrive/c/docume~1/administrator.DOMAIN/

and am able to create the RSA file... so mission accomplished... so far, I believe I'm past this, the snafu is now occurring on writing these keys to the authorized_keys file on BQBackup...

Quote:

C:Program FilescwRsyncin>rsync -av "/cydrive/c/documents and
settings/administrator.DOMAIN/.ssh/id_rsa.pub"
<login>@<host>:.ssh/authorized_keys
Could not create directory '/home/Administrator/.ssh'.
The authenticity of host '<host> (<ip>)' can't be established.
RSA key fingerprint is 18:02:d9:95:06:a9:70:74:86:b7:76:41:f6:71:a0:a4.

(<login>@<host> replacing actual login & host... it's definitely connecting)

That pesky '/home/Administrator/.ssh' pops up again. I'm not sure if that's what's causing the issue or not. I'm not even sure why the %homepath% for my administrator account on the server is set to administrator.DOMAIN, but AFAIK I can't log in to a local account on a Win2k3S box, correct?

Now, you'll notice that the command I issued to upload the keys I got from the RSync.net instructions. BQ's instructions for step 3 are pretty foreign to me.

I've gone further than this and attempted other things such as SSH'ing into my BQ server using putty and attempting to write the keys that way with no luck. I can't fully remember the errors I encountered doing so, though.
