Comment on Automated Windows Server Backups on AWS EC2 by noahlh

Hi Gavin — no, no verification of consistency — it’s just a raw snapshot output. I haven’t had any issues so far — have restored once and had zero problems. But I imagine that putting some consistency-checking in there would be a good thing (a bit beyond my know-how right now though).

The restore process for me is pretty straightforward — you use the same instance and create a new EBS volume from the snapshot(s), then assign the correct device path on AWS (i.e. /dev/sda1, xvdb, etc.) and attach the new volumes that were built from the snapshots. All seems to work fine for me. See here:

I fully recommand this doc witch had useful clues for me in the “Common Causes for “Download Failed” during Web Recovery” part, like : use de PC ethernet port instead of the LAN port

What a wonderful piece of work! Thank you not only for doing it and making it public, but also putting it on Github!

Do the scripts do anything to ensure a consistent snapshot e.g. any kind of VSS? If not. have you had any problems with backup integrity?

What would be the restore process? EC2 is a pain that you can’t just create a ‘blank’ Windows instance and attach an EBS volume as its root in the way you can with Linux instances. How have you solved that?

Cheers,
Gavin.

Before now I’ve just had to launch a new Windows EC2 instance, and ‘stop’ it as soon as it moves to

Well, I succeeded but it was difficult.
The trick : It will NOT work with a modern browser (I was using Firefox 16). I had to reinstall an old Firefox 3.6. If you do that, be careful to backup your history, or you will loose it (file places.sqlite in your profile). Good idea to save the whole profile. Then things are a bit strange :

With the TFTP server running, the firmware in the tftp root, and all verified.

First test : INVALID PARAMETERS
Try again, it will fail again.
Try the back button and you may get a 405 Error (method unsupported)

If you have this error you have won : click the reload button, and you will get the popup which warns that all parameters will be sent again, and all actions done again.
Click OK and the dowload will start.

The trick is to use a Firefox 3.6 and provoke this 405 error, then click the reload button, and click OK in the popup.

I have done this four times, it always worked in the same way.

Don’t ask me why it works, but it works (at least on my system) and I really enjoy this phone, it was worth the hours I spent to solve the problem (I got it on ebay and the vendor did not give the password).

Sorry for the typo in the first lines of my message. You should read :

I have a 6755i. I tried everything many times in TFTP and FTP but could not get rid of the INVALID PARAMETERS message.

Thanks for the article. I have de 6755i. I tried everything many times in TFTP and FTP but could get rid of the INVALID PARAMETERS message.

The ftp server is running fine (Filezilla, verified)
The tftp server is running fine (OpenTftp, verified)
Phone address : 169.254.193.29
PC address : 169.254.193.1
firmware 55i.st, put in the root directory of the TFTP server and of the FTP server.
What I entered :

For TFTP

Filename : 55i.st
firmware
TFTP
TFTP Server : 169.254.193.1
TFTP Path : (blank)

Press Enter (don’t hit the button).

For FTP
Same thing in the FTP fields, with the addition of the FTP User Name and FTP Password.

I disabled the Windows firewall
I am in Windows 7.
I use Firefox 26 and tried IE 9

I always get the INVALID PARAMETERS message.
Working on this for 4 hours.

Any idea of what can be wrong ?

Thank you for the firefox tip, I was turning insane with safari. You saved my day.
A PoE switch turned bad and 6 Aastra phones were turned on and off, so they ended without firmware, and remained in the Web recovery mode.
I now remember to have met this web browser issue with another Aastra software OMM for SIP/DECT access point.
Shame on Aastra.

This worked like a charm for me! I got a 6757i off eBay that was supposed to be factory new. While the phone was new, it apparently had been configured and put away.
Anyway, pumpkin was a little wonky at first. I was also using Internet explorer but I switched to Firefox and kept at it. After a successful firmware transfer, it takes several minutes for the phone to reboot. The first time I tried it I didn’t allow enough time and manually rebooted too early. Moral of the story: after a successful transfer, just let it sit there and do its thing! Thanks for all the tips.
