      WGS Forums Will Close on January 31st 2017   01/18/17

      Hi everyone, We're coming up to We Got Served's ten year anniversary and I've been taking a good look at the site to work through some plans for the future. I wanted to give you all a couple of weeks notice that I'll be closing WGS Forums at the end of this month.  As you'll be aware, the forums were opened to support Windows Home Server users and have done so brilliantly, thanks to everyone's participation. However, with each day that passes, there are fewer and fewer WHS deployments out there, meaning that forum registrations and traffic has now dwindled. I've tried a few times over the years to test some forums on related or adjacent topics, however, they simply haven't caught on. It's clear that these were always going to be predominately Windows Home Server forums and, with the passing of that platform, they've served their purpose well. So, please take some time to archive anything you need over the next two weeks. Access to the forums will end on Jan 31st 2017. Many, many thanks once again for your participation and support here. It's been a great community! Very best wishes Terry

Server Bare Metal Recovery Tutorial Questions?

24 posts in this topic

Hi ho,

Just a quick note to say I've posted a three part series (it just kept getting longer and longer!) about performing Bare Metal Recovery over in the WGS Tutorials section. I realize "comments" are available within the Tutorials section, but I thought it might be easier to use the forums to deal with any questions that may come up. I hope that's okay.

Here's some links to the tutorials:

BMR Part I - Backup Preparation

BMR Part II - Finding the Backups

BMR Part III - Restoring the System

Hope that helps,

-Jeff K.

Jeff, outstanding job on this tutorial! I intend to go through the test BMR later this week and will report back if I encounter any issues. I will be attempting the test headless.

Thanks for your substantial effort and for sharing it with the community.

Thanks for the kind words - much appreciated

I'm very interested to hear how this works out - I can't imagine how one works through all those WinRE questions without a GUI available - then again I've had zero experience running a headless system. Hopefully you have an spare, blank HDD to test with since I've got no idea what it might do to your existing system. Please be careful, and good luck!

Thank you for the very good and useful guide! I wonder if it is at all possible to schedule the BMR backup to run every other week, for example...

You bet. IIRC, though, WHS2011 wants to do it every day. :)

The Server Backup feature does the BMR image when it backs up. The dashboard does a basic configuration, but if you use the actual management console to set up backups, you can do a heck of a lot more stuff.

Aha, even better!

Also, is it correct that the backups stored under Stablebit Drivepool can't be used for BMR? Stablebit claims that "data is stored in standard NTFS files. You can always access your files even if the Windows Home Server completely crashes or this add-in can't be used."

the StableBit "DrivePool" doesn't use NTFS... so it cant' be backed up. But you can backup all the drives that are in the pool. In fact, that's what StableBit recommends. Though you're bsaically screwed if you want to backup more than 2TB worth of data..... :(

Ok, it's not a problem for me as I want to do BMR backups just for a system drive - I have system installed on 64GB SSD, and want to be able quickly restore it when (not IF :( ) that SSD goes south... BTW, I don't see any reason to do BMR backup for anything else... do I miss something here?..

If you want to just the System disk, that's perfect. :)

Question regarding this statement, "BMR does not have the ability to "shrink-to-fit" the partitions stored in a system image if you are attempting to recover the system to a smaller capacity hard disk than the one that was backed-up. The target recovery disk must be of equal or greater capacity than the disk it is replacing."

My system drive is a 500GB that uses two partitions -- the default action from the WHS install. I think the C: is 60GB so the D: must be about 440GB. It's a WD Blue drive, whereas I use Black drives for all my other server drives. I expect the Blue drive to fail before any of my Black drives, so when it does, if I replace it with a 1TB Black drive, how does the restore function deal with the new 500GB of disk space? Does it become part of the D: drive, or is it just unallocated space?

I use my D: partition to store the client backup database, so if I start to run out of space on D:, I may want to replace the system HDD even before I get a disk failure, so I can have a larger D: partition. I don't really want to model what it takes to replace a system drive untill its time to do so.

Thanks

@Famousdavis: if you're talking about the server backup stuff, that's completely different. That actually should be able to restore a backup to a different size.

Okay, so I'm a little confused - please enlighten me.

What's the difference between what my server does twice a day -- writing what I thought was everything it needs to build a new system disk if mine crashes -- and the ad hoc process called BMR?

I thought by doing twice-a-day backups of my system disk (C: partition and the D: partition which only contains the client backup database, no shared data folders), I was already good to go when it comes time to restore my server. Right or wrong?

Thanks

It's how it's handled. Server Backup uses a very different format than the WHS Client backups. Namely, the Client Backups use a proprietary format for storing "cluster data", while the Server Backup is basically just a VHD used for copying the system (VHD is a) what a VM uses, and B) why there is the 2TB limit for backups).

As for BMR, that just means any "full system" restore to a "bare metal" computer.

Restoring from a Server Backup basically just copies the data from the VHD and applies it to the system. the WHS client restore copies the data over the network, cluster by cluster. So you *must* have enough available clusters on the HDD for how many are used on the disk originally for that client.

That help clarify for you? If not, please ask what you need clarification on.

Just tried the links to your three tutorials but they appear to be broken.  Are they still available?

Hey,

 

I've been talking with Terry about how to get the tutorials back - he had to remove them since the code that ran the tutorial section was apparently not very secure.  I'm in the process now of digging through my local systems trying to find all the old screenies and text in case I have to re-post them all.  Stay tuned.

I certainly hope that is not what the tutorial says because it is false. You _can_ backup more than 2TB of data with WHS2011, even with the regular Server Backup Wizard. What you can not do is backup _volumes_ that are, individually, in excess of 2TB. In fact, I have just ordered two 8TB Seagate Archive HDDs for this purpose. I'll be having 2 DrivePool pools, each of 2x2TB HDDs and full duplication. I will be backing up one 2TB drive of each Pool. IMHO, if you want to backup data stored in duplicated DrivePool Pools, this is the way to do it. Server 2012 just allows you to build Pools with larger HDDs.

Sorry, but Terry has taken down the Tutorials section for security reasons. However, the Internet Wayback Machine is always a good fallback:

I have just ordered two 8TB Seagate Archive HDDs for this purpose. 

I'm sure curious to know how those perform after a month or so of usage. Please let me know.

(I suspect "atrocious performance" will be what is used to describe them... but if they're backup, that's fine.)

Interesting. What is artrocious performance and why would you expect that from these? Would they, for instance, do worse that WD Greens and if so, why?

Depends on the use case.

 

Specifically, they use "shingle writting", which means the writes are overlapped. 
Also, because of that (how they're designed), They're not going to do anywhere near as well with non-sequential writes. 

 

For a server backup, this may be fine. However, for "normal use", such as a file server, part of a pool or RAID, it may not do as well.

 

I don't know exactly, but I'd guess after a while, it would perform close to a Green drive (one of the worse models of).

But that's why I'm curious. I'd like to know how it'd work in a real world situation. Because I'm not willing to spend the money to test it out.

Ah yes, I am guessing/hoping that as a Backup HDD they'll do fine. I would expect, specifically:

- That a growing .vhd (new files within) will have good write performance as it'll write to new sectors. AFAICS, Server Backup would never _change_ files or overwrite existing data within it.

- Once a .vhd grows full, i.e. to 2 TB, all .vhds are deleted and new .vhds with just a backup of the current Server contents will be written.

 

But who knows..

 

I'll try and time backups for a bit once I actually get them. I'll report.

I've still got an HP510 Data Vault so it looks like I ought to get the KVM cable.  I was wondering whether it would be feasible to create an updated WHS 2011 Server Recovery DVD based on the original WHS v1 recovery disk.

Don't you have the install media for WHS2011? That _is_ the Server Recovery DVD. Just disconnect all drives except for the OS drive and the Backup HDD, boot from the DVD and it should be a breeze.

The HP is headless unless I get the KVM cable.  The original Recovery DVD allowed for the Server to be PXE booted and the restore was carried out from the Client.

      I have almost 10 TB in the storage pool so I was not surprised when my first server backup took a very long time (22 hrs.).  Lately the incremental server backups have been fast (15 - 18 min.)  Two days ago the server apparently initiated a full backup that failed twice but completed successfully this morning after about 23 hours.  An hour later the regular daily backup is back to a normal incremental backup times (18 min.)
      So why did the previous backup take so long, as long as a full backup would take?
      Does the server occasionally make a fresh start with a full backup to reduce the time a full incremental recovery takes?  (fewer increments, less processing time)
      I don't see a setting in the server backup options for specifying a number of increments between full backups, for example.

      Hello
      Is it possible to clone an external HDD containing the server backup to another external HDD? The external HDD doesn't have a drive letter, so how can I clone the drive? 
      I have two external drives in a Dual Dockingstation (2 drives), which has a button to clone from A to B, but I don't trust that solution too much..

      Hello
      Almost all my server backups are incomplete. When I look at the properties, I have green marks for EFI, System Reserved, Operating System and my 3 HDD's. When look in server management, I can see that the backups did complete with warnings:
      Bare Metal Recovery: could not be terminated System State was cancelled  What can be the reason? From time to time, the backup completes successfull, but very rarely.
      Shadow copies are enabled on all 3 HDD's.

      Hello
      Actually I'm backing up my Server (only 3 clients) to external USB HDD's. I'm thinking about cloud backup, and read about OneDrive, which is integrated with Office 365: 1 TB data storage.
      In case of a server damage, will I really be able to restore the server from my cloud backups? 
      Or - does this work with Azure only?
    • By rlb214
      I understand that you can't have a backup bigger that 2TB.  I have about 3.5 TB of files on my WHS.  The OS is on it is 45GB, Drive D with pictures, documents etc, is about 473 GB.  My PC backups on F are up to 1.6 TB. 
       
      I added a 3 TB WD USB drive and tried to back up only System and C.  It fails with an I/O device Error what ever that is.  Any clue what this means?
       
      How can I backup C, D, and F since they total is over 2TB?  Can I set up some sort of separate backups?
       
      Any ideas are welcome.
       
      Thanks...

    • I am running WSE2012 R2 and I only ever see red, yellow or green. I have never seen blue even when backing up. I can't explain what could be happening here, but maybe some feedback from other users may help us pin it down. What OS are your client PC's? Mine are all Win 10. Not sure if that may have a bearing.   
    • I made the leap from WHSv1 to WSE2012R2.  I like the new system but one thing seems to be missing.  In WHS v1, the tray icon would change colors to indicate various things blue - backing up now green - everything is healthy yellow - warnings detected (e.g. haven't backed up in a while) red - critical issues (e.g. recent backup failed) In WSE 2012 R2, however, I only get the blue and green indicators, even when there are critical errors on my home network.  For example, a server hard drive had failed for several weeks, but the connector icon in my system tray remained green.  I only discovered the issue when I happened to login to the dashboard for something else. Does anyone know if this feature has been removed in the latest WSE versions?  Or have I just mis-configured something?
    • I am building a new home server: I really want to use StableBit DrivePool and Scanner - am used to them and like the relative ease of use. Hardware = PC running Windows 7 Pro has SSD for OS and 5 additional 2TB HDDs + SansDigital Towerraid (model TR5M6G) connected by eSATA controller (pCie) with 5 2TB HDDs of varying age (2 brand new WD Red and the remaining 3 a combo of Hiatachi and Seagate of varying age - all test out fine for now). Towerraid is currently configured as JBOD, so I can't really see individual drives, and neither does StableBit drive pool - so I get a pool consisting 5 1.82 TB drives (the ones on the PC) and 1 giant 9.1TB drive. I have about 10 TB of data ready to go into this new build.  Will be adding more over time.  Not sure when but certain I'll have HDDs go bad on me, of course. My question(s): 1)  Is there a RAID configuration that will let StableBit do its thing watching individual drives and letting me identify sick drives that need to be removed/replaced?                           2)  If I decide to give up the RAID and just let DrivePool handle duplication, how do I configure the SansDig?                           3)  Am I just getting it all wrong from the get-go? Would appreciate any advice - thanks

    • I just posted a similar question elsewhere.  By Shadow Copies are you referring to the Windows 10 File History backups that periodically use shadow copy to backup open files? I too discovered that a huge amount of backup space was consumed by File History backups, no doubt because I was moving some large Blu-Ray files around.  That I fixed by moving the temporary and final file folders to the server, where they are backed up as part of the daily server backup.  That too, of course, uses Shadow Copies but that is another story. Has anyone done the math?  What is the equivalence .. or lack thereof ... between the traditional WS2012r2 (WHS v1 et al.) daily incremental backup :: and a Win7 System Image backup + File History backups? Restore time comparison? Which do you feel is best?
