On a single server I have four VM. All the VM are on RAID 1 with 6Gbps SAS drives with hardware RAID controller equipped with cache memory. Server capacity is 3 *900GB + 300GB
I am using native windows backup software & using portable USB 4TB HDD attached with USB 3.0. Backup is scheduled for night daily.
During the night no user is connected to the server.

As backup is taking too much of time now; I am considering to switch to NAS. Currently total daily backup size is 2TB (Full backup)

I am considering to use a NAS with RAID 0 to double up HDD R/W access speed. Would use two 1Gbps ethernet (Link aggregation)
I would map NAS using NAS iSCSI target feature with windows Hyper-V Windows 2016 iSCSI initiator feature & would schedule windows backup hoping it would reduce the backup time much.

First query: If the idea to use NAS is good enough considering the backup solution in a budget.
Second query: Which NAS should I choose:

NAS 1:  Western Digital or Netgear?
  I belive I must use enterprise grade HDD: https://www.span.com/compare/WD4002FYYZ-vs-WD40EFRX/57219-41629

how to properly manage a data center inculcate backup and vmware and exchange server ?
Organisation is organized in a pattern to flow the day to day business, every application and system is interdepended on each other and when very important “Exchange Server downtime” happened.
What is the recommended topology for a two site configuration for VMware vCenter and Site Recovery Manager?  Would there be any issues with all services (PSC, vCenter, & SRM) all residing on a single VM at each site?  Should each service be installed a separate VM (3 servers per site) or can I combine at least two of these services into a single VM (2 servers per site)?  If I am able to bundle two services into a single VM, which services can we safely bundle together?

Our environment is not too large, about 25-30 VM's in total.  I am trying to determine if I would be able to reduce disk space by bundling services into fewer VM's, but am unsure if that would cause any issues.

Thank you in advance!
I have a client that uses Outlook 2007. They have an on premise Exchange 2013. This user is the primary account that has all of the contacts and has shared them out to the other four users in the network. When you go to Contacts in Outlook, you can scroll down and see all of the intended names correctly. If you search for a contact, some of them are not indexed. An example I am using my name. I can see my name in the contacts list but cannot see the name when searching all contacts.

I have also logged into the OWA under this persons name and found the same issues. The other clients that have the contacts shared to them is working as intended although they only have read permissions to the contacts.

I have rebuilt the index on Windows 7. I have triggered the indexing inside of outlook to try to rebuild that index. I have also attempted to roll back updates prior to recent security updates for windows to see if it was a failed update. I have also exported all of the contacts to a CSV file on the desktop and can be searched properly with excel. I then tried to re-import them back and overwrite them but it made no difference.

I have exhausted all ideas and research on the net I can find. Does anyone have any golden information to offer to fix this?
There’s hardly a doubt that Business Communication is indispensable for both enterprises and small businesses, and if there is an email system outage owing to Exchange server failure, it definitely results in loss of productivity.
The Exchange database may sometimes fail to mount owing to various technical reasons. A dismounted EDB file can be the source of many Exchange errors including mailbox inaccessibility for users. Resolving the root cause of mounting problems becomes imperative to bring the server back online.

i need disaster recovery and backup for my small office of around 25 users
i'm currently running a sql server and dc on hyper v although running out of storage
i also use a nas drive
i would like to have this replicated to my home office
my office and home office has fibre broadband of around 50meg
i'm thinking maybe the following
buy 2 x draytek firewalls for home and office and setup vpn link
buy a new server running hyper v to replicate current servers to
buy something like veeam replication and backup to do the replication and backup
buy 2 x synology drives for home and office which replicate

What is the biggest problem in managing an exchange environment today? It is the lack of backups, disaster recovery (DR) plan, testing of the DR plan or believing that it won’t happen to us.

We used Commvault Simpana for several years for backup & archive.
Due to wrong decisions and configuration we ended up with a system that left our central file server scattered with stub files.
It was nearly impossible to get a view of all the files that were archived and replaced with stub files.
Top of it all we had a system crash of the commvault system with storage issues last year.

Management decided to fase out the whole system and invest in VEEAM as a backup solution and not to archive anymore becasue it was a pure vendor lockin.

We setup the VEAAM system and it works like a charm, it was a real relief to see how easy backup can be. But we were left with tons of stub files from the old commvault.
We tried recalling them which seemed to work fine if we triggered the files from the file server. The commvault plugin did not work somehow, so we had to script it to recall the files. The fastest and easiest way we found was with this command:

Get-ChildItem -File -Recurse | Get-FileHash

Seemed that some stub files did not recall and gave an error. We had to know which files were left behind and I would like to share the method we used to get this done. We started Powershell from the (old) Commvault server itself and issued this command from the root drive letter of the file server:

Get-ChildItem -Recurse |select name,attributes | Where-Object {$_.Attributes -eq 'Archive, SparseFile, ReparsePoint, Offline'} | Export-Csv …
I have a 2 VMS on Esxi using Veeam to backup on local NAS.
I would like to have replication onto 3 USB Drives for offsite purposes.
how would i accomplish the Backup Copy job using the rotated media, please advise.
Someone asked me "What are some system and network admin interview questions I should be prepared to answer?"  I have no idea.  What can I refer them to or suggest?
Hello all. I have a proliant ML350 G8 with a P420 controller running two 600GB SAS drives. The old drives failed and I have installed two new identical drives and the RAID 1 array is setup. I have a Server 2012 image backups on a Toshiba USB drive. I cannot get the restore to occur.

I get either of the following error 0x80042412 (see attached). I do know the original config had both C and D drives, but I don't remember their sizes. I don't know if it's possible to query the images on the backup disk to determine this. I know that if the new disks are smaller than the original then that's a problem, but as I said they are identical drives in RAID 1. By the way, the OS would install fine using the MS 2012 DVD and HP Intelligent Provisioning, but again I don't remember the C and D sizes and I hope to recover AD as well as files.

Any help is greatly appreciated.
I encounter a problem when I perform the SRM replication test with the message "Replication Confirmation Group Snapshot Creation Failed" and ended up failing at step 4 of the process.

The environment is as:
- 01 EMC VNX 5800 bay and 01 EMC UNITY 500 bay
- 01 Appliance EMC RECOVERPOINT version 5.0.1
- 01 VCSA 6.5
- 01 VM SRM 6.5

- 01 EMC VNX 5300 bay
- 01 Appliance EMC RECOVERPOINT version 5.0.1
- 01 VCSA 6.5
- 01 VM SRM 6.5

Recoverpoint SRAs (version have been installed on each site, sites are well coupled, consistency groups have been created at EMC Recoverpoint and replication is active.
I am trying to understand What Synthetic Full Backup backs up as data.
I thought it will create a full backup from storage and inject the incremental backup it has created the same day to the Full backup.

However looking at the Veeamone reporter, I see under Transferred (GB) column 48.13 GB,  it is less than the incremental one day before.

Any Veeam Expert to explain the report as shown in the screenshot below:

Thank you
As a very senior dinosaur I have been using Lotus 123 for a gazillion years.  It's now starting to malfunction by not functioning the way I want, etc.  Consequently and because I've previously lost some data, I think I better replace this program with something new but similar.  Can you suggest such a freebie type program to replace Lotus 123 (I'm only interested in the Smart Suite portion) with similar functions, etc.

I need to  copy data from a failing / corrupt hard drive to a new drive from a windows system.

Seems the only way to read this drive is to mount it in Linux with the -r or -ro flag (read only).

I really don't know much about linux / learning by trial an error.  I used a live rescue CD USB stick and could mount the 2 drives.

And now doing that in a Ubuntu live USB.

Now to get beyond compare installed.  I go to


and download the .deb and then the .rpm packages.  Double click on them in download folder and I get a text document most times.  On ubuntu, for the deb install, a page opens with install button!!! I click on it and all I get is an icon in the bar saying waiting to install.  

I go to the install in linux help page


and follow steps but get errors. most recently, following the terminal install commands for ubuntu,

I get:
Reading package lists... Done
Building dependency tree        
Reading state information... Done
Reading state information... Done
This package is uninstallable
Dependency is not satisfiable: libqtwebkit4

then it dawns on me - as a live install (running from thumb drive) should I be able to install apps / beyond compare?  Is there a way to enable installing on a live USB?
Hi there,

Anyone is using ShadowProtect Image Manager to replicate backups to multiple USB drives to take offsite? E.g. Rotating plug in the drives weekly.

I get some warnings and errors in ImageManager, which doesn't look very elegant, and just wondering if there is a better way of doing this out there.

I used to configure the drives so they come up as the same drive letter, however, that seem to cause some errors too, becaused some backup files dont get consolidated properly and the drives can get filled up quite quickly.

See screenshot attached, we have 2 * 2TB USB drives, now showing up as G: and H:, while one drive is plugged in for replication, the other one is offsite, not sure if doing it this way is any better.

Any tips and tricks would be appreciated.
Using Outlook 2013 with Office365. Large groups of email are missing. In the inbox sorted by date descending there a re big gaps of mail missing. Last month had quite a bit missing, more missing from the month before, then large gaps of many months with no email at all, then some from a year ago, then some from a couple years ago. Did the restore deleted items from the inbox and that restored a lot (mostly recent from the last couple of months)

Also receive this same O365 account to an Iphone and an Ipad.

I suspect it might be IOS device since I had a similar problem a while ago but in that case you could watch the email go away.

Any suggestions would be greatly appreciated.

Thank You
Background Information:

- We have two separate but identical sites (Production and Disaster Recovery)
- Both sites will have their own infrastructure of 3x servers, 2x iSCSI switches, and 1x SAN
- Data from production site will be replicated to DR site quite regularly (may be real-time)
- Sites utilize VMware ESXi/vSphere 6.5 and will have Acceleration Kits

We are in the process of an infrastructure upgrade, and am in the planning phase of implementation.  Once we have all of the above fully implemented, how can I configure a proper fail over and fail back configuration?  I am pretty sure I may be able to configure High Availability on a single site for a failure of a single host; would it be possible to configure some type of fail over should a disaster completely bring down an entire site (if building hosting production equipment burns down)?

Is it even possible to utilize VMware High Availability to fail over to another site/SAN?  If it was a temporary failover (power at production site is lost, then comes back), would there be an automatic fail back?

Can I use this method to temporarily take down a site for maintenance while having no impact to end users?

Thank you in advance for any assistance provided.
We have a hard drive that was working but now we get d:/ is not accessible.  Access is denied

It has been a while since we've used a service and I remember it wasn't a good experience although the details escape me and I won't bias people's answers with who the company was.

Could people offer their recommendations on companies that could potentially get data off a 3.5" WD drive from 2009. It is SATA. There's no encryption on it.  And it has been a while since we've used a service. What is the going rate these days along with lead time for the less expensive service?

And am I missing anything while I tried connecting to my computer, it shows a drive letter, disk management says it's NTFS and healthy. But when you click on the drive letter in file explorer it says D:/ is not accessible Access is denied.

I had hopes it was an NTFS permissions issue. I booted RescueCD, a linux product and googled how to mount external hard drives from the command line - I would have thought there's a way from the GUI?

I got the following message:

The disk contains an unclean file system (0,1)
Metadata kept in windows cache, refused to mount
Failed to mount '/dev/sdd1': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown windows fully......
or mount the volume read only with the ro mount option.

We aren't up on Linux. Is there another product we should be using?
Hi Experts,

I have A Database on SQL server 2016 SP1 on Primary site and another SQL Server as a DR server in DR site. DB is very small one and data growth is also small. DB is less than 1 GB right now and there may be about 1GB per month growth.
Connection between Primary site and DR site is 2Mbps dedicated
I need almost real time replication like Oracle RMAN sync [Oracle active data guard or data guard]

SQL and windows server - Microsoft SQL Server 2016 (SP1) (KB3182545) - 13.0.4001.0 (X64)   Oct 28 2016 18:17:30   Copyright (c) Microsoft Corporation  Enterprise Evaluation Edition (64-bit) on Windows Server 2016 Standard 6.3 <X64> (Build 14393: )

What would be the best SQL Server replication method except SQL Server Always on ? I need your opinion for DATA replication.

Hardware level, VM level replication will not work.
