Great article that explains the importance of not just relying on definitions based security solutions. Thanks for writing this. Interesting read!

10 Tips to Protect Your Business from Ransomware
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

So a customer accidentally formatted a 2TB hard drive to NTFS. I used the usual techniques to try a recovery but nothing worked (Testdisk, Ontrack).
After discussing with him it looks like the drive was previously HFS.

I was wondering if this new information can help me? I never tried a recovery from HFS but I don't think it should be very different with Testdisk.
i want a solution to back up my Microsoft exchange 2016 database and enable me recover mailboxes. i have gotten to end of life on Evault and we are retiring the services due to cost implications. any recommendations?

Note that i have a DAG set up on premise and i intend to do a direct back up to Azure, But that does not solve the problem of recovering mailboxes or old  emails.

I have a Dell Vostro laptop with a 500 GB SATA hard dive
-      My client accidently spilled water onto his keyboard but did not pull out the battery while attempting to remove as much water as possible from the keyboard. He let it dry over night before actually pulling out the battery the next day
-      He let it dry out a few more days.
-      Powered up the laptop and it posted “No Boot Device”. Confirmed the BIOS does not see the HDD
-      He brought the laptop to me
-      When removing the back cover to view the hard drive, I saw some rust and corrosion on the controller board. I removed the controller board to clean off any corrosion on the board and contacts. Reconnected. Still, the pc post shows no hdd connected.
-      I then inserted the drive into a USB HDD dock. The drive would spin, makes a couple of “clattering” sounds but never see the drive
-      No backups
-      He also stated that the laptop has never been dropped

My question is
-      Is it worth trying to locate an identical hard drive and transfer the controller board to the defective hard drive? Like I stated above, the drive does spin up. I’m just wondering if the circuit board is damaged, which I’m sure it is -  is it possible to get the drive to be recognizable by the computer?
-      If not, I will have to send out the drive to a data recovery center

  • Summary
  • We have attempted to run Microsoft Azure Site Recovery (ASR) - Hyper-V Replication without success.
  • We are running Windows Server 2016 with 3 VMs
  • The ASR service has been installed by an external service company
  • We have been able to successfully complete the initial backup of the servers to the cloud
  • However the system  cannot keep up to date with the amount of changes on the server
  • All the upload bandwidth is being saturated (80 Mbps) and not keeping up with changes
  • (See attached screen shot of message from ASR)

These are the answers I received from the service company to my questions:
1. Could you tell me what the replication method we are using is called.
Azure Site Recovery - Hyper-V Replication
2. What the problem is. Is it the MySQL databases?
We don't know if it is the MySQL Databases for sure. As explained before the problem is too many changes are being made and the Azure servers cannot keep up with the constant changes.
3. Is the problem correctly described as being too much “data churn”?
I have forwarded the screenshot I had of the exact error message. (see uploaded image)

The service company cannot resolve the issue and say it is up to us to solve the data churn issue
They have asked Microsoft for help but they say they cannot because the issue is likely with …
Is it OK ?

At the least I would have thought the PCB was to be avoided

The drive needs to be data recovered before it was handled but it struck me as careless handling .....
I'm looking for the best tape backup devices that plugs directly into an RJ45 network and that can be used with backup programs such as Veeam, Backup Exec, and Microsoft Data Protection Manager (DPM) that can backup Server 2016 and VMware networks.

I'm looking for a self-contained tape backup device that doesn't need to be connected to a server using a SCSI, USB or other method and that plugs directly into an RJ 45 network with a network cable. I'm also looking for a single tape backup device since I will be able to manually swap out the tapes as needed.

I have a unique small business network that requires that tapes be used to store the backups.

What are the best tape backup devices that can do this? We are more than willing to purchase used tape backup devices.
SQL Server, like all other major RDBMS, supports ANSI SQL, the standard SQL language. SQL Server also contains T-SQL and its implementation. SSMS- the SQL Server Management Studio known as Enterprise Manager earlier is SQL Server’s main interface tool supporting 32-bit and 64-bit environments.
Testing some backup images we have for older servers after a disaster recovery scare. I have a System Image backup from a Windows 2008 R2 exchange server that gets generated by our backup system (Ahsay) using windows server backup

I am trying to test the restore file doing a bare metal restore on a virtual machine on hyper-v 2016

I run through the 2008r2 install media, repair your computer, re-image, load the image from the network, and am immediately hit with the following error:

The system image restore has failed.

Error details: The device is not connected. (0x8007048F)

I can't seem to find any details about anything like this on the internet. I am wondering if this backup is bad? Theres literally nearly nothing for this specific error in this specific instance anywhere that I see. It doesnt help that the error itself is incredibly vague.

There is only one virtual hard disk attached to this machine, and it is larger than the source computer's hard disk.

This is my first deep dive into using Windows System Images so it's quite possible I just don't understand how to do this correctly, but from what research I've done on line, what I am attempting to do should not only be possible but completely straightforward.
There's a request for "Change runbook" that documents/records changes from Day 1
so that in the event of bad changes (malicious or inadvertent ones) being introduced
over along the line of changes, we can rebuild a server/system back selectively,
dropping the "bad" change so that we can bring up the system to a "clean" slate.

Was told it's not "Change Control" nor CRs that we are looking at here.

I've suggested that a 'bare metal' backup be done with incremental backups (think
EMC has one such product) but this is not what the team requires.

Any document, tools or method are much appreciated.

I have a Windows hard-drive from my previous computer that got corrupted in a very weird manner.
All the files in the hard-drive had their size capped to 64 KB (I connected the hard-drive to my existing computer via an external adapter).
No files seem to be missing from this hard-drive, but file sizes range from 0 to 64 KB, but never more than that.
If a file was originally less than 64 KB, e.g. a small text file - I can view it normally and all is great.
If an image file was, say 2 MB, I see it as 64 KB, and when opening it in a photo viewer - it shows the image's first couple of rows of pixels, and then the rest of the image is corrupted.
Other file formats, e.g. a large DOCX file that now appears as 64 KB large cannot even be opened.

I don't know enough about Windows filesystem and how file-size is computed / stored in the file system,
but it seems like the table that stores the file-sizes somehow got corrupted, or maybe some other attribute of the hard-drive got corrupted, like the allocation unit size ? (shooting in the dark here).

It just seems like all the data is still in tact in the drive, but not reachable because the file sizes got messed up for anything over 64 KB.

Any help would be extremely appreciated !
Need to buy a USB To SATA Hard Drive Adapter kit. What's a recommended adapter kit?  I need to recover data from an old SATA drive to my Microsoft Surface Pro Laptop.
Data integrity is the paramount concern when determining any form of a disaster recovery related solution. If a solution cannot preserve and guarantee the integrity of data placed in its trust, then the solution is of no value to an organization.
I have a Server 2016 Hyper-V base server with 6 Server 2016 Hyper-V virtual machines that I need to backup.

What is the best Veritas Backup Exec product and licenses to purchase for performing this kind of backup?

Will purchasing Backup Exec from the URL below allow me to do a complete backup of this server or will I need to purchase additional licenses or options?

I have lost  ‘.xml’ &’.docx’ files from 32GB pen drive. The main folders are still there but sub folders disappeared. I was not expecting this as the pen drive was working fine on my Mac. Is my pen drive affected by some virus? Can I restore missing files from a pen drive? I am running macOS High Sierra 10.13.6 Please help!
I need to install Microsoft Data Protection Manager (DPM) to back up a Server 2016 Hyper-V base server and the 10 Server 2016 virtual servers that are running on this base server.

I already have a Server 2016 virtual server setup with System Center Configuration Manager (SCCM) 2016. Is it best to install DPM on the base server, on the same server running SCCM 2016, or on its own Server 2016 virtual server?
Please provide me with guides on implementing & configuring Microsoft Data Protection Manager (DPM) backup within a Server 2016 Hyper-V environment that has a Server 2016 base server and 6 Hyper-V virtual servers & that will be backing up to a NAS.

I need to make sure I can successfully restore the entire base server and all virtual servers if necessary so that no configurations or data is lost in the event of a restore.

Hello EE,

I am trying to explain to management the need for a fire suppression system in the new data center.
I am being asked to provide a representative timeline and milestones to get a data center back up in the event of a fire.

Does anyone have a real life example as our options are:
1. fire suppression
2. enough bandwidth to mirror all sites to another site so could work remote via VPN (but the bandwidth for 1TB-2TB files can easily offset a fire suppression system cost)
Dear Experts Exchange,

I have some old JPG files since 2003, which were corrupted I think straight from the camera (Canon Ixus). I have kept them because I hoped one day I would find some tech that could recover the underlying images as they are of the family. Can you help?

I have tried a bunch of jpg recovery apps over the years, and sent them to an 'expert' once too. No joy.

I see you have a case where someones corrupted disc had 0x0 resolution jpgs. And it seems to have been fixed. Can you help me?

I have added some example jpgs below.

Don't have much documentation at my new place and I wanted to know where to begin to understand our DR/BDR information.  I specifically wanted to know what it costs the company to be down for an hour or a day and so forth.  Since we don't have much documentation, it is really hard to understand or where to begin.
I have a LG Gram with 1TB of SSD.  It is partitioned into drives C, D, E, F, and G.  It stated acting really funking following some sort of uSoft C++ update yesterday.  It would lock up, or be really slow, or OK performance but the cursor would constantly blink with a action "circle."  So I reimaged from a Acronis True Image image of two weeks ago.  TI says it has successfully been restored, but it will not boot.  I figured out the BIOS entry, but regardless of boot order it falls down to "Start PXE over IPv6".  I have been struggling for two days, so decided to give up and just do a factory reset, but cannot find how to trigger that.  Meanwhile, I came across WIN RE, which might fix my boot issue, but I cannot find any instructions on how to get into WIN RE except by first selecting it then restarting from Windows 10.

I would like to give WIN RE a go before I go the nuclear route.
Attempting to restore 200r2 server from Windows Backup on a 2TB Seagate Portable HDD and recovery isn't recognizing the drive.  Not only that but the server is either not booting or booting extremely slow when the drive is even plugged into the server.  I can plug the drive into a Win10 machine and it's recognized (and can see the data on it) normally.
