Disaster Recovery

Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.

I remember there being something you can wipe on your eyeglasses  --before using-- to prevent them from fogging.  Anyone remember what that was?
Hi Guys,
I have 2 site in 2 towns. There are some vm on site A that will be replicated on site B and viceversa.
There are DC, file server, and a pair of ERP based on sqlexpress, and other vms.
I have not yet decided which hypervisor to install and I am open to advice.
My question is how to deal with IP management?
The best solution is to have same IP server subnet on site A and site B excluding VLAN streching that is DEVIL.
In your environments do you have any VM's that you do not backup as a matter of course? Our admins have sent through 'what we currently backup' in Veeam but a quick cross match to a list of all servers in the domain show some servers are not being backed up at all (which may be purposeful - hopefully!). I was just interested if this is common and examples of VM's where you don't need to backup the configuration/data?

Also in your experience - how easy would it be for an admin to miss something critical in terms of VM/virtual HD in backup selections? Realistic or very rare?

Does anyone have something that will allow the below step #4 ?

 1. currently a library has 20 Window 10 Pro PCs
 2. every night a software like one of the below software packages are run to REFRESH the PC back to the original IMAGE
         ** https://docs.microsoft.com/en-us/windows-hardware/customize/enterprise/unified-write-filter
         ** https://horizondatasys.com/reboot-restore-rx-pro/
         ** https://centuriontech.com/enterprise/
 3. about four times a year I manually update each of the 20 Window 10 Pro PCs with a new version
     of special locally installed LIBRARY software / etc that is not already on WSUS, Ninite, etc
 4. instead of doing the above #3 I would like to just update ONE PC,
     having the image easily CLONED to the other PCs
         ** I am willing to have everything on a HyperV VM on each PC if needed
So, I have two data centers.  One is in Houston and one is in Colorado.

In each data center, I have one Hyper-V stack.  Several hosts, many VMs in each data center.

I'd like to send replicas from data center 1 to data center 2 over our internet connection.

Now I do this internally, between sites, etc, but this is my first foray into doing it between data centers over the net.

So, should I do it this way or not?  Obvousily I'd use certs.

Is there a better way?

Is it just a matter of directing 443 to my hosts and making my connections?

Lots of questions and I'd like lots of feedback.

I know it'll be tough to assign points and points hardly seem worth replying to such an overbroad question, but hey, I LOVE EE so here I am.

Speak oh wise ones!
Is there any free hard disk data recovery tool ? I find Stellar can read the data but it seems that it is not free.. Any recommendation ?

if we're taking backups daily ie every 24 hours (timings
of the backups (the backups can end between 1am to
4am, depending on how much is there to backup),
what's the RPO (Recovery Point Objective) we can
commit to?  24hrs or 30 hrs or it's 48hrs?

In the current risk management doc, it's indicated
 as 48 hrs but since I joined not long ago, checking
if this is correct?
DB2 10.5 on Windows Server 2012 R2

I have a HADR setup with 2 servers.  Right now if my primary server crashed, I would log into DR server and make it the primary, then change the DNS alias to point to the DR site.  This would take between 10 and 30 minutes (roughly).

My boss has suggested that we should look at Automatic Client Reroute instead to make this quicker and more efficient.

From what I have read this has the following steps.

1. Update the alternate server setting on production to point to DR.
2. Update the alternate server setting on DR to point to production.
3. Set up time out criteria on both to control fail over.

The way I understand this is that when this is configured, the DB2 server will set up a config file on the clients with this information and when there it a communication failure, the client will start trying to connect to the alternate database.  There are also settings on the client that help to define when to switch.

So, do I have the gist of it?

Now for my questions.

1. Do any of you have experience with HADR and ACR?  If so do you recommend it?
2. Since I have HADR set up, I would still need to issue the takeover commands manually to bring up the standby server as the primary.  Is that correct?
3. Although it seems like I can control the failover timing, what I have read it not real clear.  I'm not sure I want a client to redirect to the DR server after just one communication error.  How controllable is this?
4. I …
Because the Win 8.1 did not start, even if I tried all kind of solutions, I arrived to Refresh your PC from blue troubleshooter boot screen as seen here:
I used the Win8.1 installation files on USB stick to do that refresh, which in the end solved the problem.
The main consequence is that I lost the list with the programs previous installed and of course their settings too.
1) What can I do now to recover those programs and their settings?
Is the only solution to use a dedicated recovery software that scans the SSD and tries to find the previous installed programs? If yes, what software do you recommend?
I have now on my desktop a .html file/list with Removed applications done by Windows during Refresh your PC time.
Program files folder are empty now.

2) The Windows folder is around 11GB now.
Is that normal?
What size should it be after new install?
Is 11GB size similar with a new installation or is it bigger because contains some files and settings from previous install?
But I have Windows.old folder. It is around 25GB.
I found next article:
How would that help?
For data recovery, I need to reinstall Windows 2003 server to a set of new drives on a Dell Poweredge 2600 server.   During install it asks for the drivers (F6) on a floppy drive to do the installation.   Don't have any of the original Dell disks.   I have tried downloading from Dell but cannot find what is needed.
I need to restore a system image on a server 2012 R2 machine.

I've booted recovery options from a 2012 R2 Disc, but re-image wizard says Windows cannot find a system image on this computer. Ive read this is a common issue.

The image was originally saved to a nasbox and i pulled the entire "WindowsImageBackup" folder from it onto the root of an external hard drive.
If i cancel the error and browse for driver, i can see where file explorer sees the external drive with the folder in it.

How to i make the recovery wizard see the backup folder and continue the restore?
Regarding SRM 8.5 to be used with Storage Array Based replication using Recover point on vSphere 6.5

How to get this fixed so that SRM is visible for further configuration
VC 6.5 U3 is also running as  appliance  

Please help to fix it -Thanks!!
Hi Experts,

I am programming stuff using Caspio tools, since they only provide revision history to some of their features, I had requested we invest in a custom program that will connect online and perform that in a scheduled bases (as manually its possible to accomplish that from their site).

I had mentioned to our manager that its very useful when debugging stuff to know when exactly did a certain problem started to occur.

and this was manager's response.

...I still don’t get how back-ups will help in troubleshooting. Is it more than just back-ups?

Perhaps you can point to a place where this usage and benefit its being clearly explained in a more professional way.

In addition I would like to have an idea what could cost such a task (writing a script that will logon to our Caspio account and perform the export).

Hello, I have an Ipad Air that will not do anything I have left it on the charger for a day, also I tried to do a hard reset holding the home and on/off button with no luck. Is there any way I can get the data off the drive my customer really needs some pics and data off the system?
Despite listening to "an Expert" (e.g. storing valuable data in the Cloud, or at least on three devices!) my brother has lost ALL his family photos stored on an USB External Seagate Drive Enclosure. (for the last 20 years!)

The USB device is detected within the OS (Windows 10), but displays the disk as Not Initialised, and also the size in Disk Management is 3.89GB and not 2TB.


1. Do I just send off to Recovery Firm ?

2. Try and do something myself, and if all fails Do 1. above ?

I've removed the disk from enclosure and luckily (I think ) the 2TB Seagate is a normal SATA device, and not a USB modified hard disk.

Any ideas to successfully recover, gets the points.

Interesting observation the disk makes a pulsing buzzing noise, like it's trying to spin up and stops, but does eventually get there....and power up this occurs via the original USB enclosure and a USB caddy system (USB).

I may connect direct to a SATA bus.
A user has a Transformer T100TAF, it's an ASUS product.  The computer runs on Windows 8 and has stopped booting.  Looking it over, I found that it had been dropped.  It looks like the motherboard is cracked.  I don't see a drive-in here, so I assume that the SSD is soldered in place, though, I've not identified which chip is the SSD.

If I can ID the chip is there a reader that I can use to get the data off?

I'm searching the interwebz and I'm not finding a lot of great answers, though, someone out there must be able to do this kind of thing.
We have an old laptop that has Windows 7 and some very specific software that our finance dept uses. We no longer have access to this software that was created by company that is no longer in business. Users typically remote into this machine to run this software that requires SOAP UI Utilities and Office 2003 to work. We would like to Clone this PC unto another similar PC so more than person can access this software and perform the same function. All that being said, can we close the hard drive of that laptop unto another laptop (Does it have to be the same make and model?) so we can have an exact duplicate of that system? I was thinking about using Clonezilla.
We are considering hosting our own cloud backup location for a handful of servers that are hosted by commercial companies.

Looking at 150 GB of data backup per month and a monthly OS disk image of three or four servers approximately 200 GB total.  Most of it is archival and the image files would be rotated possibly maintaining 2 images per remote server at a time.  Currently using AWS with SyncBack.  Unfortunately started with Jungle Disk because at the time SyncBack did not interface directly with AWS.  This has led to enormous expense in retrieving things from Glacier and dealing with Jungle Disks changing file names/data to proprietary scheme so you can't see actual file names in Glacier.  And JD does not have Glacier retrieval function.  The server hosting companies charge almost as much for regular image backups as for the monthly server fee and I have heard that their backups are not totally reliable.

In spite of that very costly situation and the recent cost time and money required for us to retrieve a 5 TB archive, AWS charges too much and they have a ridiculous amount of tiers of charges and fees that it is nearly impossible to know what charges are coming on a monthly basis.

Looked at Azure and it looks slick but it isn't free or inexpensive even with our moderate amount of usage.  So we are considering hosting our own cloud backup.

We have extra servers so no hardware expense except a few large drives.  We would figure out some secure VPN / FTP into the…
Hi I have a user that's Outlook PST file became corrupted.  I have never seen this before, but the file now has a .corrupt extension.  I tried to use my typical Outlook data recovery sofware packages, even scanpst.exe, but they get lost, I think they want to find a pst or ost.

question, how would I go about recovering data from this.  This dude uses a Surface so he ins't part of the network and keeps his stuff locally.

Thanks all.
I was working on organising some 112 zip folders containing some training files that I purchased recently. These were located on an external 3 TB Seagate hard drive (separately powered).

When I was almost done, I suddenly noticed that all except one of the folders had simply disappeared.

I have been desperately trying to find those files, thinking that perhaps I may have accidentally moved them to another folder, but no, those files no longer exist on that drive.

Currently I am in the process of running chkdsk /h /f /r /x on that drive and hoping something would come up. Besides a friend suggested it could be that the allocation tables are corrupt so I might have to resort to expensive data recovery tools or services.

Any help would be welcome from this forum please. Those files together cost me about $800!!
please guide me about below:
1. what 3rd party tools can be used with
   vmware/ hyper-V for DR replication/mirroring. and how these tools will work. agent will be installed on each VM ? for real-time replication
2. how licensing work in DR case. windows server, exchange, SQL etc
3. what are the best backup practise? weekly, monthly etc ? kindly explain those practises
I google drive backup a safe backup solution?

We have a corrupt exchange .edb file that we need to recover email from.

I have tried the exeutil soft recovery option, this did not work. I havent tried the hard recovry yet because the file is 600GB and reading up say its takes 3-4 hours per 3GB ish, this would take an ice age so im exploring other options first

The edb was part of a Raid 10 array that 2 of the drives for some reason marked themselves as foreign. We have to clear the virtual drive and reassign the disks to the new VD. All the data is still there. I dont think this is a factor but worth mentioning just in case.

The idea I had was to use some third party software that claims it can mount a corrupt edb and get what I can, but I cant even copy the edb file to another drive as it keeps failing saying the file is corrupt.

Any help or advice I could get at this point would be very appreciated.

The database is currently marked as dirty shutdown. I tried reading how to make it a clean shutdown but couldnt seem to get anyhting to work.

Thank you
