Exchange 2016 DAG:

Originally I planned a 3 node DAG. But 2 of them are at sites that are regionally near each other and power or internet isn't common, but still not completely uncommon. It has only effected one of the sites 90% of the time, I'm but worried about that last 10%.
If something did effect both of them I'm left with 1 vote out of 3, and if I understand Microsoft's documentation correctly in an odd numbered DAG the FSW is ignored, and the vote would still be split event if it did use it.

So my revised idea is 4 node:
(Site B and C are my concern above)
Site A - 2 Nodes
Site B - 1 Node
Site C - 1 Node

Site D FSW
Site E Alternation FSW
(Site D and E are completely outside the region for all nodes, but it's not realistic to place a Node there)

So I already know this will work, my question in, lets say Sites B/C are down.
I'm left with 2 out of 4 nodes plus my FSW. Now lets say some idiot restarts my FSW or it just goes down.
Does my Alternate FSW take over with no downtime under these conditions? Or is there a period of being dismounted?

I understand that with all nodes up my FSW makes no difference in uptime, I'm just speaking about losing my primary FSW with 2 out of 4 nodes down and my Alternate FSW available.

_________________________

And actually second question, lets say I only had a primary FSW, 2 out of 4 nodes are down, FSW goes down the database goes down that I know. My question is when that FSW come back up can I remount the …

Cloud Class® Course: C++ 11 Fundamentals

This course will introduce you to C++ 11 and teach you about syntax fundamentals.

Someone showed me the Shadow Explorer app (https://www.shadowexplorer.com/) and claimed that the Shadow Explorer program allows you to obtain past versions of all files within your Windows 10 OS that are located in any location on your hard drive (not just in the locations that are shared).

Is this true? Do shadow copies actually backup the contents of the entire hard drive's files? I can see how this can be possible since an initial backup would be done and then subsequent backups would simply backup new file as well as any changes that were made to existing files. However, on the other hand, it seems like this would be limited due to the Disk Space Usage "Max usage" section of the System Properties' Protection tab (see the screenshot).

So is it true that shadow copies actually backup the contents of the entire hard drive's files and that by using a program like Shadow Explorer past backups of files can be recovered (based upon the days and times that past shadow copies were performed)?

Hi, I was looking for instructions on how to decrypt a drive that was crypted using veracrypt.  Like if I put the encrypted hard drive in another computer and wanted to decrypt it.

I tried dooing that today and got lost.  Also do I just need the password they use to log on the Veracrypt screen, or do I need to entire encryption key.

Thanks all.

Good day-
I have an Ntfs volume from a failed server 2003 (not a typo). The volume was RAID1 and a member file server.

Ntfs permissions are keeping me from accessing previous versions - although I can see the previous versions thru explorer.

Any tools you can think of or am I dreaming?

Exchange 2010 Recover Server Error.

I am trying to recover an Exchange 2010 server using the setup /m:recoverserver option.

While this has worked for me in the past in other environments, I am getting the following error related to: - RoleDomainController

I have tried recovering the server as a domain controller and as a member server.

Anything I can do to get around this error?

Below is the output with error bolded:

Hi Experts

I have a 3TB tape with media ID "A00005" that includes some VMs backed up end of March 2018 using NetBackup server "XY01" (Windows 2012). The site including the server has been fully decommissioned. However, lately I received a query that requires to restore a certain VM from the tape. I have another NetBackup server "XY02" (Windows 2012) that I could use. But "XY02" already have a record in the Catalog with media ID "A00005" which includes weekly full backup for different things. Honestly I just received the administration and I have no clue about this, just bits and pieces I picked up reading while trying to find a solution. The backup device is a regular tape drive. How can I restore the VM without disturbing anything else?

Kindly assist with step by step (layman terms) on how to accomplish this task. Indeed very grateful for any insight.

I have a HP ml310e gen8 v2 server with 2 disk raid.Disk 2 had failed and i decided to replace that drive I shut down the server and replaced the drive. the server would not boot replaced the old drive and the server still wouldn't boot. i ran the acu and it says the raid is ready for rebuilding,  after the server initialises the raid card it says  1778 drive array assuming automatic data recovery process. this is with the the failed drive. it then goes through a disccheck  and moves on to  automatic repair.and I seem to be going around in circles. i am not great in raids so I must have screwed up someplace. is there any way i can get the working drive back running again?

I'm curious about opinions on actual experiences with Veeam Failover/Replication vs VMWare's integrated solution.
Preferably from people who have done both and some Pro's and Con's, overall experience etc.

We already have Veeam and I'm quite happy with it for backups, but I'm not 100% sure about it's failover capabilities.

We are looking to set up a point to point vpn with sonicwall on our end and watchguard on the clients end. We'll be using that to set up crashplan backup on virtual machines. Two questions.
1. Is it pretty straightforward to set up the point-to-point between sonicwall and watchguard?
2. Once that is established, would we need a backup device for each VM (say we have 3) or would backing them up to one device with designated partitions work ok?

Hi

We use VMware and VEEAM backup. Due to some database corruption on our Windows 2008 Exchange 2007 server, I am planning to run Eseutil /P and Eseutil /D on the server during this weekend.

The total size of the Mailbox database on the exchange is 365 GB and is hosted on D: Drive and the available free space on this drive is 800GB. I am planning to take a Snapshot or Clone the Exchange server before I run these Eseutil utilities.

After running these utilities, in case the database get into a problem and if data loss occurs, I can bring up the Cloned server OR the Snapshot.

In my situation please let me know what would be the best CLONING or SNASPHOT?
Any suggesting would be great!
Thanks in advance

Hi,

Yesterday I unlinked OneDrive Personal to link up my OneDrive Business. I normally don't use OneDrive Personal but when my new computer was setup my personal account was linked (desktop, docs and pics). It synced alle my files and said it was full, I continued work on it since I thought it was stored locally on the computer.

I did a lot of work on a file stored at my desktop, which I saved multiple times during last week. Yesterday I unlinked the OneDrive Personal and linked up OneDrive for Business. Today I was going to edit the file again, everything was lost and it shows only the content of the file at the beginning (before edit started)

How can this be? Somebody else heard of this, found a solution?

Dear Experts

We are looking for backup and remote replication to achieve the  business continuity and disaster recovery at present we have server with vmware hypervisor we have vmware essential plus Vm running application server, understood from expert exchange expert we can achieve it though vmware essential plus, also we got proposal from the Quest BACKUP AND DISASTER RECOVERY SUITE- Rapid Recovery Soultion,  with Rapid Recovery solution, we can do following below given features:- Bare Metal Recoveries, Rel-Time Backup, Zero Backup Window, Near Zero RPO, virtual stand-By-Hosts, Compression, Dedupe and Encryption, Replication and DR .
would like to understand the difference between VMware disaster solution and Quest BACKUP AND DISASTER RECOVERY SUITE, if we go for vmware does it require vmware license at the recover site also in additional to primary site license, looking for cost effective solution please suggest .

Dear Experts

We have to setup  an application server which is web-based (LAMP stack) for which we are planning to procure the server with 10TB disk and with vmware hypervisor , the application  server will be running on VM, it is very much important for us to setup a disaster recovery and business continuity for example if server crashes or due to physical damage at head office (primary site)  goes down then  the  server at recovery site to ensure business continuity.
 we have 2 branch offices one connected with mpls vpn to the head office where this new server going to be setup and another office is having leased line connectivity. please suggest on the following and which is the best one recommended you can add other plans please
1. while purchasing the dell server is there software  if purchased and as well procure same identical config one more server and host it in the branch office, hence 2 servers of identical configurations and the software will mirror the volume and data - if primary site goes down the recovery site comes to live for the business continuity

2. OR should we have to look for automatic vm backup with veeam and this can be configured replicate from the primary site to the recovery site

please suggest thanks in advance.

Hello EE,

I scripted a simple import of csv with applicable headers  as per below  , with an rloc grouping . ' rloc' is the record locator . powershell group "values" output below.

How would I go about selecting specific 'segment types' example , NAM, FLT etc to reconstruct this into a specific data format as show immediately below this line . Each one will be outputted into an individual txt file for further processing. I have also attached sample data file .

EE Pros,

I have struggled over the years with backup devices and backup software.  I have some specific questions about a Seagate 4TB drive I just bought.  First of all, while the box sells the device as a cloud enabled solution, the cloud portion requires a separate fee with Seagate instead of a internet connection with the $150 device.  

Here are my questions;

When using the Seagate Dashboard, if you back up your harddrive, you get this incredibly long number that represents a backup.  The way I use to do it is  to have a DATA file on my harddrive and simply copy the DATA file over to a backup drive.  My hunch is that in order to back  up ONLY CHANGES to the Datafile on my harddrive, using the Seagate software, I must put up with the long number rather then  my own file names.  Is that true?  If so, I can select back up at a frequency, for example, "daily" and it should only refresh the changed data. Also, can I restore this data to another Windows 10 system or do I need to image the entire drive?

Any insight into proper tactics in backup and restore procedures would be appreciated.

Thank you in advance.

B.

When creating a recovery image for my Microsoft Surface, I am supposed to start by creating a USB recovery drive and then download a recovery image for my specific Surface. This download is a zip-file, and after having decompressed its content, I am advised to drag all these files to the created USB recovery drive and replace all files in the target. However, in the decompressed Surface folder I find dozens of folders that seem to be language specific having names like "fr-ca", "hu-hu", "it-it", "ja-jp", etc. (See attached screen dump). Do I really need to drag all these folders as well over to my USB recovery drive? Is it not enough to only include the language folder I want to install?Screen capture of recovery image folder content

I'm having trouble wrapping my head around a clients DAG config.  They have a 5 Node DAG, 3 MBX servers in Primary Site and 2 MBX in Secondary site, no FSW.  Cluster Quorum is Node Majority.  When Primary site goes down, DAG copied in Secondary site goes Offline as Quorum is lost. What can I configure to have the DAG Copies in the Secondary site to stay operational?  Even if I put a FSW in the Secondary Site, the Cluster will ignore is because it's a 5 node cluster.

Azure has a changed a lot since it was originally introduce by adding new services and features. Do you know everything you need to about Azure? This course will teach you about the Azure App Service, monitoring and application insights, DevOps, and Team Services.

I have a server running Server 2012.  I made a backup of the OS drive, and it is broken up into the following:

Backup 2018-03-19  021305
Catalogs
Logs
SPPMetadata Cache
Medaid

Now if my server crashes, how do I take these folders to re-install to bring it back with all the settings?   Is there a step by step list on how to take these folders to a bootable disk and then re-install.   the server has a Data partition that is saved to the cloud every night,   The server is split into a raid 1 and raid 5.

I have a Samsung galaxy S6 (SM-G920F) from a friend. The display is broken (black screen). And additionally the cell phone is locked. :-(
So I can not make a data recovery/data transfer to another device since all is locked. I have tried Wondershare AND FoneLab software. There is a need to make a special order of pushing the home/power/volume-up-buttons. It onced worked, but not more anymore. Any other ideas how I can get the old data ?
(the cell phone is not rooted, USB-debugging is NOT turned on, I also tried OLG-USB keyboard to connect with no luck)

I have a PC at home with Windows 10 Home.  I have the primary OS hard drive; I only put OS related things on this primary drive.  I also have 3 other hard drives of varying sizes/brands; they are large sizes too that hold my Steam games, movies, TV shows, music, photos, etc.

How do I backup all my hard drives to one hard drive?  Does Windows 10 home have this already?  I believe I would need to get some 2-5TB hard drive to hold all the collective data from each hard drive, but what software should I use to accomplish this?  Will this software do regular backups?  I'm open to free and paid software recommendations.

I have a Kingston 16GB usb flash drive that does not show up anymore when I plug it into any computer.  
I have tried the flash drive in 4 different computers, bot PCs/Macs, and it's not recognized.  Is there any software out there that anyone knows of that will help me recover my data?

Here's what I tried:
Software:
https://www.icare-recovery.com/
https://datarecovery.wondershare.com/

Both of the above programs does not recognize the flash drive.

Here's what I've tried so far (no particular order)
1. under disk management (when I plug in the drive, a "removable" K drive does appear, and when I unplug it, it disappears
dskmngt2. under device manager, I updated the drivers for the root bridge
3. under disk management, I did a right click on hte K drive and did update drivers there as well
4. did a diskpart, list disk, and disk 8 shows no media, 0B, 0B for both size and free (I'm assuming same disk as in disk management), I tried to select the partition, but nothing worked
5. I went to kingstons website and googled for data repair software, couldn't find anything

Not sure what else I can do?  Any ideas?  I really need to get the data from the usb drive.

Hi,

I have a micro sd card for my dash cam, it was working(recording) before I dismounted it. I have tried different card readers, no luck. One of the EEs suggested me to use a smartphone to see if it is readable. I tried, it worked for a short period of time.

I was wondering if EEs have any suggestion for data recovery service.
It is a 64G sd card.  thanks

Just a follow up "opinion" question.  Once I received the expert advice I needed, I was able to restore a "bare metal" backup of my server that I had taken early in the morning on the day I got the virus attack.  Now that everything is working and "back to normal", I'm rethinking my backup strategy and have gotten opinions from a number of people about a number of different products.  My question is this.  Since I had such success restoring my server using the "built-in" Windows Server Backup feature, I'm wondering whether or not to use the "built-in" Backup and Restore features in the Control Panel for my Windows 7 and Windows 10 workstations.  Does anyone have any experience with these utilities (which claim to create a complete system image) and any opinions as to why I shouldn't just use these "built-in" backup utilities rather than spending more money on another company's backup solution?
