AWS - two questions pertaining to AWS, or hosted services.  First off, I am trying to get an idea if AWS is a cost effective hosting replacement solution for small business where in house they have anywhere from 1-6 servers, from a cost perspective.  I took a peak at some of the sizing tools for AWS, but not clear on how I would assess throughput, if all daily functions were moved to AWS.  Would you also move all infrastructure servers and clients would authenticate to DCs in the cloud?  I am not sold on this at all, but it makes absolute sense to know the pros and cons.  From a control and cost and security perspective it probably still makes more sense to go with in-house servers for small business, but need to confirm.

Secondly - what is the best way to get familiar with AWS, for small Windows environments, trying to see if it makes sense from a business continuity stand point. For example, currently using Veeam to replicate all VMs to another remote host, so if we lose site A, we can spin everything up within minutes.  Any thoughts on best way, to get a good understanding of AWS?

Thanks guys!!!

How delete an app that is locked?

I no longer use CrashPlan, but can not delete it, since it's locked. (Mac)

CrashPlan Locked
I can not log in since the account is gone.

I do seem to be able to access CrashPlan Service Preferences, but doubt they would do anything since there is no connection to the host.


We have been using a Seagate STDR5000200 external hard drive for backing up data from our local PCs and servers.

This drive was encrypted with Bitlocker.

While we were backing up data to this external hard drive, the PC, which this drive was plugged into, was turned off accidentally via a switch on the wall.

The next day, this drive was not recognised on the PC it was plugged into and after trying different Windows 10 and 7 PCs, I found that there could be a problem with this drive.

I used Seagates error checking tools and Seagate said from the result that this drive is not functioning properly.

Through the Disk Management on one of the Windows 10 PCs, I did "Rescan disks" and the corrupt drive was listed as "disk 6 unknown".

Right clicking on the disk 6 gave me the options; Initialize disk, Offline, Properties, help.

When I tried "initialising" the disk or clicking "properties", the Disk Management window freezes and eventually the disk 6 disappears from the PC.

Errors I received from this were : data error (cyclic redundancy check) and i/o device error.

Is there a way of formatting this drive?

I have a client who set up a Seagate Blackarmor NAS box a number of years back.  It has 4 Seagate 4T SAS drives in a RAID-5 configuration.
I was in their office last week and took a look at the device as it was running very slowly.  I looked at the front panel information (scrolled through the menus) and all four drives were listed as "Good".  The volume was listed as "degraded".

I looked at the web interface and saw that drive 3 was no longer part of the array (not sure if it said offline or bad).  I used the Action button to remove it.

I have since rebooted the box and now the volume is shown (on the front panel) as "Failed".  All four drives show as "good".  On the web interface, all four drives are listed as "good" but there is no volume shown.  I'm hearing no odd noises from any of the drives.

The client's backup is not as recent as he'd like, so he is very interested in trying to get this back up.  I realize that the safest option is to go to a (rather expensive) data recovery service.  He's not likely to want to go that route.

If these were NTFS-formatted drives, I'd have numerous options to analyze and possibly recover the data.  I'm assuming that the box runs Linux and that's not something I deal with except in very rare situations.

One option is to replace the drive that was removed from the array and see if it will recreate the volume.

I'd appreciate any suggestions on how to proceed.
Veritas Backup Exec 20.3 fails backing up System State since upgrading OS from Server 2008 R2 to Server 2012 R2.
Local drive backups work ok within Backup Exec, just not system state, a failure occurred accessing the writer metadata.
Vssadmin list writers shows all VSS services in a stable state
Wbadmin systemstatebackup works fine.

I did read that this can be caused when the Windows Recovery Partition is missing from within Windows Disk Management.
This is the case, yet wbadmin works ok, and I have 2 other identical servers also upgraded which work fine in Backup Exec
I am running into this issue on a Xenserver 6.5 Installation.  I'm looking for an expert who can help recover the disks or guide one of our IT guys on a way to investigate it more thoroughly.

Our Xenserver installation is running into the following error:

The problem is when the virtual machine boots it shows this error in console:

Boot devide: Hard Disk - failure: could not read boot disk

No bootable device.

Additionally XenCenter storage tab reports the size correctly but shows occupied space is much larger than it should be.  We moved all the remaining working VMS off the machine, and it's still showing the same occupied space size.  Path also does not show up correctly.

I need someone who can diagnose and correct the issue of VDI not available, VDI failed to load immediately.  Someone who we had working on this says that the "identity has been lost"

This is really far beyond my expertise and am hoping that there is some sort of way of saving these VM'sShows that 99% of the drive is used. Other image will show that the VMS are no where near that size including the snapshots.image-2-.png
Hello Everyone,

I am trying to recover data from a faulty hard drive. I would like to clone the HD before starting the data recovery process.

does any on recommend a fantastic software to clone hard drive bit by bit. if free even better thank you for windows OS.

Thank you,

We have a laptop and due to GDPR, i have to encrtpt the laptop with Veracyrpt.
The staff had kept very valuable data on the Hard disk  desktop and didn't back it  up...

The laptop was not booting poperly and i removed the hardisk and and connected to the hardisk caddy to see if i can recover the data and unfortunately it detects the disk if i open , it says i need to format the disk before i use it.

If i clcik cancel it says F:| is not acessible, the volume dosent contain a recogonised file system.Please make sure that all the required file system are loaded and that the volume is not corrupted.
I tried mounting the hard disk through Vera crypt software and also using the rescue disk still it doesn't work.

Please help , the staff will be the most happiest if the data is recovered.
Any help will instructions will be great.

I have a clients 2TB Hard Disk Drive that is failing.  My W10 PC can still read the Recovery partition OK but slow.  There is one file on there that I was able ot copy over to my drive.  However the main operating partition is showing up as a Drive on my PC but there is no partition showing.

I have tried to get GetDataBack for NTFS to read the drive but it comes up reporting significant unreadable sectors and then cannot read any data on the main partition.

I am wondering if there is any other software people recommend to attempt data recovery from a failing hard drive.  

I would like to do everything I can before I need to recommend to client to take the drive to a Clean Room at significant cost.
Hi ...
After creating a bootable USB  using "etcher" utility from ISO files on a USB flash drive, the USB drive becomes the same size as the ISO file and cannot add more files. Moreover, inserting it into Windows OS , the usb key is not recognized anymore. Is there a better utility supporting any kind of bootable ISO files and still be useable to add more files to it.

Just for full disclosure, I've already posted this question on the Western Digital community forums, but I've come to value the level of contributions and input from the Experts' Exchange, so I wanted to share my experience here to see what else I might hear from any of you.

Recently, I discovered a disheartening problem with a piece of my equipment, and the prospects for straightening it out aren't great, based on my own research. Long story short, I have a WD Passport portable hard drive that has been working pretty decently for the better part of the last ten years since buying it at my college's bookstore. Unfortunately, I had a mishap while my device was in transit: carrying it in a box up a staircase, it started to slip out as I got up the stairwell; I managed to make it to the top in time, but the hard drive fell out just as I got past the threshold of the door. My intent was to hurry inside to carefully set the box down, or at the very least have the fall be cushioned by the carpeted floor rather than have it tumbling down the hardwood staircase. It seemed pretty harmless at the time, so I didn't check it immediately that night. but over this past weekend, I needed to hook it up to my computer, and I found that it wasn't working anymore. I immediately did some online digging and found that this is pretty common; not only that, I've seen WD
What power outage TRACKING systems do you recommend that would do what my
currently does, but every 1 minutes instead of every 15 minutes ?

My UPS is plugged into a natural gas "always on" generator, therefore the UPS would show a 5 hour
power outage only lasting about 30 seconds, just enough time for it to switch over to natural gas

V3700 Remote Mirroring

vmWare Essential Plus V5 - 2 hosts
Storage Lenovo V3700 v2 - iSCSI

I Need a solution of Disaster Recovery, so I will acquire other storage V3700 and active the feature called Remote Mirroring.  With this solution, all datas will be replicated in two storages.

Imagine the primary Storage fail. What will happen to VMs?
How do I configure vmware essential plus to VMs will be running in other storage ( mirrored)

I am currently doing off-site testing of our backups and having a minor issue I was hoping someone could shed some light on or point me in the right direction for resolving.  We are a school district and our backup needs are not the same as a for profit business, so we are doing a mixture of backups both using backup exec, as well as nightly full backups using Windows Backup on a few 2008 R2 machines. Such as 1 domain controller that holds our FSMO roles, and our Mail Server which is hosting exchange 2010.

My problem is, when I restore the DC in our test environment, FRS is not up and running for several hours because it cannot find the other 2 domain controllers we normally have in our production environment. So AD is not fully up and running.  After a few hours of sitting, it magically starts working and event logs showing FRS is no longer preventing the machine from being a DC.

Is there something I can do to quickly resolve the issue in case of a real DR situation?  Once its fully up, I just do a metadata cleanup and remove the other DC's replicas in my test environment, but can't do that until FRS is up and running.  Any help would be greatly appreciated!  =)

Trying to restore data from a NAS drive. So i have this Bufalo NAS Terrastation, and the fan died, so i am trying to recover the data from, usually, i just use something like knoppix, but when i boot Knoppix up with drives attached, it doesnt see the drives, it must be something to do with the Raid thats installed, i can see the drives in the BIOS no problem and they have passed all tests ( i was worried with the fan not working they may have overheated)
We are restructuring the ownership of documents with new staff/teams being formed.

We currently have IT Applications teams (who run IT Quality Management & still running it), IT Security Governance
(new team), IT Infra Ops.

In general practice (or commonly adopted out there), which team or person owns the 4 documents below:
1. IT Application Delivery Framework :  applications PM, IT Security governance, IT Quality Managemt, or ?
2. Vendor & Contract Management Framework : applications team, IT Security governance, IT Procurement or ?
     (a mix of IT applications, infra, security vendors but most of the vendors are applications vendors)
3. Project Management Methodology : applications PM, IT Quality Management, IT Security governance or ?
4. DR Plan : We don't have a DR team;  so hv to choose betw IT Ops, applications team, IT Security governance or ?

Any authoritative references (eg: NIST, big four consulting firms papers) will be helpful.
I have a Hyper-V Server 2016 setup (the free one).  I experienced a system failure and have to rebuild.  How do I create a system image backup for disaster recovery that I can use when I boot up to the server setup and choose system recovery image?  All the information I can find expects a full Windows server install with GUI.

I have a Lexar Flash Drive, 128 GB and I need to do some data recovery.

Any suggestions on software that I could use, or is a professional service preferable?

Hi All,

I have a dilemma and wanted to get some feedback.

We have some Hyper-V server hosts that are lease is up and management is sending them back to Dell and a new Hyper-V server is being built as we speak.

The issue I am most concerned about is that the FSMO role holder virtual is on the Hyper V host that is going back.
This VM is currently backed up daily with VEEAM.

Here are the options for moving and or removing this server off of our host that is going back and not taking down our whole Active Directory.

1. Move FSMO roles to Physical 2016 DC, and move DC to new server and import into new host.
2. Restore Virtual to new host with VEEAM. ( I am concerned with different versions of Hyper V backing up and restoring too)
3. Demote the DC all together after transferring FSMO roles and rebuild new DC on new host.

The reason we use a virtual is because of back up.  I back up the physical DC but only C drive and system state.  VEEAM backs up the whole DC.

Any thoughts or new suggestions are appreciated.

Thank you,

Setting up the back up server for Azure backup on Prem, I get the notification "You are not connected to the internet" . Has anyone encountered this errors when registering an op prem server for Azure backup and recovery.
What are the differences between Veeam Backup Standard, Enterprise, or Enterprise Plus software?

And what is a perpetual license agreement compared to a subscription license agreement?

We use Seagate STDR5000200 external hard drives for backing up our data on our systems each month.

These systems we backup data for would include Windows 10 Pro, Windows 7 and Windows Server 2003, all systems are using BIOS.

The Seagate STDR5000200 external hard drive we have contains every piece of data for our business such as databases and Microsoft office files.

We prefer to keep our external backup drive portable so that we can bring our external drives offsite.

This drive is replaced each month at a time by another drive which contains backup data where we switch between two drives each month backing up our systems.

These external hard drives are formatted as NTFS.

These drives are recognised by all our PCs.

We have had a problem with these Seagate external hard drives where, if we have a backup running and the power of our PC goes off, the drive becomes corrupt and we lose our data.

This has happened with our Seagate drives more than once.

What would be the best external hard drive to use for backup of our system's data that is fail safe and portable?

Artificial Intelligence
We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.
