VSS System Writer is not found on this system 2

Hi,

The VSS System Writer is not found on this system:

I have already posted above error solution:

http://learnbackupwithmoin.blogspot.com/2016/02/the-vss-system-writer-is-not-found-on.html

Also I observed some error along with this error:-

Also check if you get below error type:-

Error :- No Error

Error:- 61320:save: Cannot bind socket to connection port in configured port range on system "Client Name": The requested address is not valid in its context.

Error:- 98266:save: The VSS System Writer is not found on this system.

Also check below test:-

vssadmin list providers
vssadmin list writers
vssadmin list shadowstorage

We found that in some case vssadmin shadowstorage/writers/Providers are not configure properly.

NetWorker client file index database Size

For the NetWorker client file index database (nsr/index): The number of files
indexed and in the browse policy. This is normally the largest of the NetWorker
databases. For storage sizing, use this formula:


Index catalog size = {[(F+1)*N] + [(I+1) * (DFCR*N)]} * [(1+G)*C]


where:

F = 4 (Full Browse Period set to 4 weeks)

N = 1,000,000 (one million files for this example)

I = 24 (A four week browse period for incremental backups - minus the full backups)

DFCR = 3% (Daily file change rate for standard user file data)

G = 25% (estimated annual growth rate %)

C = 160 bytes (Constant number of bytes per file)

For example:

{[(4+1)*1,000,000] + [(24+1) * (3%*1,000,000)]} * [(1+.25)*160]

{5,000,000 + [25 * 30,000)} * [1.25 * 160]

5,750,000 * 200 bytes

= 1,150,000,000 bytes

= 1150 MB

How to check validcopies in NetWorker 9 with mminfo

How to check validcopies in NetWorker 9 with mminfo:

In your backup environment data clone going to a disk media, I suspect that we are rarely will see a save set with clflg mminfo attributes. The reason is that 'faulty/aborted' save sets will automatically be deleted.

If you want to know whether a save set has successfully been cloned you better check with 'validcopies' mminfo attribute:


mminfo -r "client,name,ssid,validcopies,pool"

or to verify all save sets with only one copy

mminfo -q "validcopies<2" -r "client,name,ssid,validcopies,pool"

EMC ELECT 2016

Friends I would like to share that I am elected as EMC Elect 2016 with another 70 experts from 150 finalists.

Below is the link for your reference to see the list of elected candidates




This is a very funny incident with me about EMC elect. When I started working on EMC product and I heard from someone that there is one kind of election EMCElect. I was very surprised because I thought EMC is also conducting election like politicians  but after reading about EMC Elect I got to know that this is an honor for EMC expertise.

So that time I was very excited to grab much information about EMC Elect. I always share my knowledge regularly on EMC Community Network, sharing on Twitter too. I also started sharing my technical tips through blogs and on EMC community forum for knowledge sharing.

I was shortlisted For EMC ELECT 2013 but was not selected, and I took it as a challenge and I said to myself that next time I will take more efforts and again participate in 2014 and finally I got first EMC honor in 2014 and again in 2016.

I would like to thanks all who voted me and fulfil to complete this program.

This is unique initiative by EMC and I am really enjoying to participate year again year.

Special thanks to Mark Browne ‏@DathBrun and all known unknown people who were involved in this activity.

VSS System Writer is not found on this system

The VSS System Writer is not found on this system:

While backing up Windows 2008 and 2012 server on EMC Networker and you are getting below error, there will be many causes for this error. This is a very common permission issue.


98266:save: The VSS System Writer is not found on this system.  The backup is stopping because the System Writer is required for a successful system state backup.  Have the system administrator check the VSS infrastructure and fix the issue.

You should first try below solution:

Start or Restart below services:

1. COM+ Event System
2. COM+ System Application
3. Distributed Transactions Coordinator
4. Microsoft Software Shadow Copy Provider
5. Volume Shadow Copy service
6. Networker remote exec service

And try to take test backup, if it fails again then you should go with below Microsoft solution.

The system writer fails because permissions to files in the %windir%\winsxs\filemaps\ or %windir%\winsxs\temp\PendingRenames directories are incorrect.

Solution:
To resolve this issue, type the following commands from an elevated command prompt:
Takeown /f %windir%\winsxs\temp\PendingRenames /a
icacls %windir%\winsxs\temp\PendingRenames /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\temp\PendingRenames /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\temp\PendingRenames /grant BUILTIN\Users:(RX)
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)


net stop cryptsvc
net start cryptsvc


Type the following command to verify that the system writer is now listed: vssadmin list writers


If the system writer is missing, check the Application event log for the following event
