Everyone knows that surfing the web can/is/will always be a dangerous thing to do.  As a systems engineer/administrator we always have the task of protecting end users who are educated on the security risks and the end users who have no clue at all.  No matter how much knowledge you have as an end user you can always get hit by doing something very innocent on the Internet.  But what can be done to help prevent this?  For myself, I registered with the elite group over at MalwareURL and started importing their database into my firewall.  Now this does not protect me 100% but it sure helps to say the least.  To date they have 33,944 domains listed and 8,787 IP addresses listed.

Here are the two best reasons to check out MalwareURL.  First of all, you can use their information to infect a virtual/physical machine to practice clearing out nasty little bugs and teaching yourself how to reverse engineer problems.  Just remember to infect a test machine, not a production box.  Second, you can also report any sites you find that are not listed yet.  This helps build the database and the best way for us to protect ourselves is to share information with each other.

I recently implemented Commvault version 8 with a company that was running Symantec Backup Exec.  The Symantec software was having trouble backing up the Exchange mailboxes (Exchange 2007) and this was a mission critical issue for the executives.  The Symantec software was also having a difficult time backing up Server 2008 and Citrix Xen Server.  After numerous calls and emails (18 calls and 22 emails) to tech support it was still not resolved.  So now the company was missing a massive amount of data and could not get the software to backup to an IP NAS device (Seagate Black Armor).  In the end this would have spelled disaster for the IT team and there would have been some very bent employees with a very bad taste in their mouth for the IT staff.  I made one suggestion…Commvault.  I used it in the past as a stand alone and in conjunction with Exagrid disk storage.  I loved it very much and wanted to get it in house ASAP.

First step was getting the management staff on board after showcasing it for the Director of IT/IS.  The Director loved it and only had one thing to say.  “Prove it in the first month of use and I am sold forever.”  The budget was approved and the purchase was made.

Second step was scheduling the fun of turning off Symantec and kick starting Commvault.

It was a warm fall day in 2009 and Myke the Master Geek went to work in his workshop.  I started by disabling the Symantec service on all servers and disabling the software on the backup server.  Next up, getting my Commvault Media Agent and Commserve on-line and ready to go.  The Media Agent was a new Dell R710 loaded with Server 2008 64 bit with a Powervault connected to it.  Then we added 2 Seagate Black Armor 4.5TB devices for the disk storage.  The Commserve was actually a VMWare virtual server loaded with Server 2003 32 bit.  Once the devices were loaded, connected and talking…it was on to deploying the agents on each server to be backed up.

The ultimate goal was to have about 4 weeks of backup data on disk and then a weekly full backup on tape.  We had a decent size of data that was backed up daily so we purchased the deduplication license with our Commvault software.  This would allow us to deduplicate our data and use less disk space for our backups.  With that in mind we expected a disk savings of about 50% to 60%.  We were wrong and wrong big time.  After running the Commvault backups with deduplication for about 2 months, we were getting a disk savings of 89.88%.  We were storing 10.074TB of data on 1.019TB of actual disk space.  That was saving us 9.055TB of disk space.  We were very excited about this as this gave us a great amount of room for growth and gave us a baseline to look forward to in the future.  Needless to say, the Director of IT/IS was very happy.

So with backups running to disk and tape now we had to verify that everything worked as planned.  So I began to test restores of data.  I started by restoring data from disk back to file servers, mailboxes and SQL servers.  Everything worked as planned and with great speed.  Now I began the tape restore process.  I selected a file and the software came back and told me what tape it need and bam, there it was…restored.  I tested about 35 different files ranging from SQL to Exchange to general Office file types.  Everything worked as planned and promised.

To this day everything has worked perfect and we have been very happy with our backups since.  This has saved on restless nights of sleep having nightmares about backups and restores and it has dropped our stress level by a huge margin.

Thanks Commvault!

I would also like to say that the new Dell R710 server runs like a champ and is a solid server.  We are also very pleased with our low cost NAS devices from Seagate, Black Armor 440.

p.s.  If you are from Symantec or really like Symantec and find this post to be offensive…good.  That is exactly what it was meant to be.  Once Symantec bought Backup Exec, the software fell apart and has fallen way behind the times and needs of the IT/IS world.
