Synology NAS as Time Machine Backup Target Tip

This is a quick tip on using a Synology NAS to backup with Time Machine in OSX Lion / Mountain Lion.  If you have installed and are running the Synology Antivirus Essentials app, it is advisable to exclude the Time Machine backup location.  You can do this by creating and running a ‘custom scan’ instead of running a ‘full scan’.  If the antivirus makes any changes to the time machine sparsebundle it will likely cause the backup to become ‘corrupted’ from OSX’s standpoint, which will cause OSX to need to create a full backup again causing the loss of your backup history.

Sophos Antivirus for Mac is a good real-time scanning platform that you can use to protect your OSX based machines and it’s free.  http://www.sophos.com/en-us/products/free-tools/sophos-antivirus-for-mac-home-edition.aspx

Bit Defender for Mac is also offered in the Mac app store and as with all Bit Defender products I’ve come across offers solid and superior protection.  It’s free and can be used to scan your drives, however I did not see the ability to conduct specific items scans or provide live protection.

Good luck and hope this helps someone out.

Apple Time Machine Backup on Synology NAS Fails

Specific Error: Time Machine could not not complete the backup, .sparsebundle is already in use

I began backing up my Macbook Pro to my Synology NAS since I didn’t want to lug around an external disk with my laptop.  It worked seamlessly for a week until one of a few things happened that caused the backup to fail in mid-backup.  I either powered off the system or the system went to sleep during the backup.

Upon restarting the computer, I received an error message when Time Machine once again started to do it’s thing.  The message read: Time Machine could not complete the backup, .sparsebundle is already in use.  When I searched the error, I found easy solutions for people using an external drive while connected to an Airport Extreme and backing up to a drive attached to that.  It involved simply killing the user sessions that were associated with the drive and in a few cases rebooting.

My Experience: The Synology DS1511+ NAS is Purely Rock Solid

12-26-10-synology-15tb-nasI’ve been running a vSphere lab of my since ESX 2.x.  Over the years, I’ve used both local and NAS based storage with varying degrees of satisfaction with the results.  In the case of NAS storage, which is required since I can’t afford a SAN, I looked at Synology devices over the last year trying to gain the motivation to make the investment.

Needless to say, I dove in with both feet, and maxed out a Synology DS1511+ with 3TB drives.  I purchased my Synology DS1511+ from SimplyNas with the drives included, including their burn-in testing, and I haven’t looked back.  The device has been up and running since October 2011.

Squeezing Maximum Performance Out Of Your Iomega IX4-200D as a vSphere Storage Target

I’ve been using a few Iomega StorCenter IX4-200D’s as storage targets for vSphere 4 ESXi and have been a little disappointed at the performance.  This disappointment really only comes when VMs are booting, I’m using Storage VMotion, or consolidating snapshots.  For the price point, it’s still a great piece of equipment and I can honestly say that I’ve had 17+ active VMs running off the unit with no problem once the VMs are up and running.  Keep in mind this is a lab implementation and those VMs weren’t under heavy utilization.

I’ll keep this post updated with anything else I come up with or that is submitted in comments.

Edited 10/23/2011 – No longer recommending use of NFS as a vSphere target on this unit.

Using the Iomega IX4-200D as a Storage Target for vSphere (ESX and ESXi) Lessons Learned

StorCenter_ix4_200d_hi_328x188

I’ve been using an Iomega IX4-200D as a storage target for vSphere and have to say that for the most part it works well.  I’ve used it both as an iSCSI target and as NFS storage.

You can and should expect it to suffer typical storage performance issues.  It runs on 4 hard drives, mine in a RAID 5 array which is not the most performant, but best in case of disk failure and who wants to lose VMs.  It’s still a limited set of spindles to work with and keeping that in mind will save you troubles down the road.

At one point, I had 17 VMs running on a single IX4-200D.

Still interested?  Keep reading…

Remove iSCSI Drive Lock From Iomega IX4 Series NAS and vSphere Without Rebooting Either

000

Is your Iomega NAS iSCSI drive locked by vSphere and you don’t want to reboot?  This works with vSphere 4.1 (using ESXi but should be the same for ESX versions), and an Iomega StorCenter ix4-200d (firmware 2.1.38.22294).  If you encounter issues with another version, please let me know.

I’ve had some trouble off and on with iSCSI on my Iomega IX4 series NAS.  The trouble exists around removing the iSCSI target from vSphere but not releasing the hold on the NAS typically requiring a reboot of both the NAS and the host to remove the lock.  As I don’t like taking my host(s) or NAS down, through a little experimentation, I’ve come up with the steps necessary to remove the target allowing for the editing or deleting of the iSCSI drive on the NAS.  While something is connected to it, the IX4 will not allow editing or deletion.  This also works for removing a single target drive while vSphere is still pointing to other targets on the NAS.

Let’s get to it!

Get Windows 7 Working with your Terastation

Windows 7, along with Windows Vista, both have issues interacting with Buffalo Terastation and similar Buffalo products.  This is due to updated NTLM security settings in both Windows 7 and Vista.  The un-patched behavior is continued prompts to log in / authenticate to the NAS.

Buffalo has released a registry patch that allows Windows 7 and Vista to connect to their Terastation NAS products, by lowering the security level to Windows XP compatible NTLM security.  This is a downgrade, but I have thus far had no problem with it.  Check out the readme below that’s included in the download:

This registry patch files enables Windows(R) Vista(TM) PCs to
work with Buffalo NAS products.  This patch is installed
directly onto Windows Vista PCs.

WARNING:  This file is only for use on Vista PCs, it is NOT
required or supported on any other operating system.

Compatibility:
This patch is only required when using one of the following
Buffalo NAS products:- LinkStation (HD-HLAN)
– Gigabit LinkStation (HG-HGLAN)
– LinkStation Home Server (HS-DGL)
– TeraStation (HD-DTGL/R5)
– TeraStation Home Server (HS-DTGL/R5)
– TeraStation Pro (TS-TGL/R5)

Instructions:
1)  Double click on the Buffalo_NAS_Vista_Support.reg file
2)  Press the ‘Yes’ button when prompted.
3)  Press the ‘OK’ button to exit the patch file.
4)  Restart your Vista computer.

SECURITY NOTICE:
Applying this patch lowers the NTLM authentication
level to be compatible with some of Buffalo’s NAS products.
This NTLM authentication level is equivalent to the level
used in Windows XP.

Add NAS folders to Windows 7 Libraries

I found this entry in a forum: http://www.sevenforums.com/tutorials/4617-libraries-include-network-folder.html and wanted to keep easy access to the information.

As people begin to use Windows 7, Power Users and even regular users will eventually get around to wanting to expand their Windows 7 Libraries, which I think is an incredible feature, to include NAS locations.  Household NAS’s are now less than $200 for a terabyte, and home users and business users alike are going to be looking for this functionality.

Currently, Windows 7 does not support adding NAS locations to libraries.  I’m not sure why, but hopefully Microsoft deploys that functionality some time very soon.  Apparently, these locations break the Windows 7 backup functionality for that library.

Here’s the quick and dirty for the method I used.
