- 6. Meeting the Recovery Expectation We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP
- 7. • Users expect to up 100% of the time just like "FaceBook" or they expect outages to be minimal - Minutes of downtime, not hours • Meeting this expectation means that data can no longer be "restored" - The network transfer is too time consuming • Data have to be recoverable "in-place" and it has to be readable the first time - Verification We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP Meeting the Recovery Expectation
- 8. Meeting the Zero Data Loss Expectation We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP
- 9. • Users expect you to have every copy and version of their data protected all the time. Just like "DropBox" • Traditional once-a-night backup is no longer enough. Too much data is created, modified and potentially deleted in a day • Backup has to occur at multiple points throughout the day, potentially hourly, without impacting performance We are live tweeting and answering questions using hash tag: #DellDP.

- 11. • Tape makes this difficult because you have to manage time expectations. Disk makes this difficult because you have to manage expense expectations. - Try Tape, Require scalable deduplicated disk • Users expect you to keep all their data forever, near-instantly available...for free • Reality is that 99% of the data will never be needed again. The problem is you don't know where that 1% is going to come from. We are live tweeting and answering questions using hash tag: #DellDP.

- 13. 13 How a large manufacturer moved to meet disaster recovery challenges We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP
- 14. 14 Rob MacCara • System Administrator, Maritime Paper Products, Ltd., Nova Scotia • 30 years of IT experience • Built his own company building, selling, and maintaining Digital Video Surveillance systems for both small and large retail customers • 20 years in the Royal Canadian Navy as a communications technician specializing in computer systems
- 15. 15 Maritime Paper Products: manufacturing market leader • Major corrugated box manufacturer with multi- continental reach • Factories across the Canadian Atlantic provinces • Forward-thinking with both automation and sustainable manufacturing • Massive daily output
- 16. 16 Maritime Paper’s business-critical applications • Peak summer periods have us running 24 hours a day, with three shifts • We depend on: o Domain controller o Microsoft SQL Server apps o Microsoft Exchange Server • A server failure can stop everything and close plants, resulting in potentially very large revenue losses Rob standing in front of one of Maritime Paper’s high-speed box fabricating machines
- 17. 17 Challenge of a failing legacy backup scheme • Time-consuming rotation of tapes, full backups to removable disks • Older server population prone to major failures • Day-long file recoveries • File backup only • Virtualization effort In Maritime’s high-volume production environment, the pressure is on to deliver to customers on time so their customers are also on time.
- 18. 18 Time for a change Virtualization was the last straw • Existing backup software wasn’t up to the task • Choice seemed to be either an expensive upgrade or having to settle for greatly reduced backup capability Maritime reached a point where its existing legacy system would require a costly upgrade.
- 19. 19 Looking for solutions Key requirements We looked for an advanced backup and disaster recovery solution that: • Worked across virtual and physical servers • Reduced recovery times • Restored to any type of machine • Included replication
- 20. 20 Why we decided on Dell AppAssure A ”night and day difference” • Strong ROI and a wealth of advanced backup and recovery features • No more tape • Recoveries in minutes • Simplified recovery offsite
- 21. 21 Results • 95% savings in storage space • Minutes to recover lost file versus 24 hours with our previous data protection product • $28,000 savings in software and hardware
- 22. 22 Fast forward to today A strong DR, migration and testing solution • Pair of virtual AppAssure Core machines for local and offsite recoveries • Push-button failover to virtual • Simplified creation of DR site • Fast restores at any level • Rapid P2V and V2V migrations • Faster DR testing
- 23. 23 Recovery proof point Recent primary domain controller’s RAID backplane failed • Resulted in a major crash • Up and running in less than an hour as a virtual machine, including troubleshooting the server • Avoided: o All–nighter o Panic o Revenue loss • Costs and staff time would have been much higher without Dell AppAssure
- 24. 24 What we learned Now we know: • Our data is safe • It’s being continually backed up

- 32. 32 The Power Company’s Recovery Objectives • RPO - They can stand up to one day’s loss of data – Data can be re-input if necessary for time lost – Backup to both disk and tape provides multiple fallbacks if necessary • RTO – They need to be back up and running in 8 hours max. – Bare metal backup and recovery restores O/S and applications – SmartDisk and/or tape provides recovery of data We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP
- 33. 33 What is special handling? • Exchange, SharePoint and databases either have to be stopped or have some method for a point-in-time backup to be able to recover it. • Active file systems require snapshot capabilities for accurate backup • Virtual machines can be backed up as either a client or as a VM • Use of plug-ins requires backup as a client, not a VM.

Join us at tweetchat.com/room/DellDP
- 40. 40 The Web Conference Company’s RPO/RTO • RPO - They can stand up to one day’s loss of data – Clustered servers means one can fail, others in the datacenter will fill in – Other sites can cover if a data center is lost – If data is available at another datacenter, it can be spun up quickly • RTO – They need to be back up in 1 hour max. – Time is money! – Standardized server image allows quick duplication of a server – Customer setup data is only important part of recovery We are live tweeting and answering questions using hash tag: #DellDP. Join us at tweetchat.com/room/DellDP
- 41. 41 How We Did It.... • NetVault Backup has the capability of easily making a duplicate of a backup – It is built into the backup setup window – Just takes a few clicks – You can specify where you want the duplicate made – You can specify how you want the duplicate made – By the client – By the server • SmartDisk became the target to allow very fast recovery We are live tweeting and answering questions using hash tag: #DellDP.

Hinweis der Redaktion
- My first introduction to the industry was punch cards and programming in Hex - after that, I knew I’d rather work on the hardware side of things. Then, along came the IBM PC and I was hooked!Along the way I started a business building computers and providing service to businesses, and then shifted focus slightly to the video surveillance market and started building DVRs.I also did twenty some odd years in the Royal Canadian Navy as communications technician - primarily in a support role working with Windows and Unix networks in the naval engineering school – where the big difference between that and a civilian school, is that in the Navy you can tell a student to sit down and pay attention – and they will!A few years after I retired, I ended up working for an amazing company located in Nova Scotia, Canada.
- I’ll tell you a little about where I work, so you can get an idea of where we were before starting on the disaster recovery path.We’ve been a major corrugated paper folding and converting manufacturer (or as my son says, “a box factory”) for more than 80 years, and we’ve currently got a workforce of about 125 employees working between four plants located in each of the Canadian Atlantic provinces.From the inception of the company, we’ve looked at the way we manufacture, with an eco friendly and sustainable view. We even have a line of 100% recyclable and FDA approved wax alternative coatings to prevent boxes that used to go to landfills, to now go into the recycling stream.Our market is concentrated in the north eastern part of the US & Canada, Cuba & the Caribbean, and north western Europe.We have a number of machines that can output mind numbing amounts of boxes: up to 25,000 boxes an hour– it’s a staggering amount and they all haveto be tracked right from the making the corrugated paper through till the finished product gets loaded into containers, for shipment by truck or ships to final destination.
- Peak summer periods have us running 24 hours a day, with three shifts.We depend on Sequel, Exchange & BES, domain controllers, terminal servers, and file & print servers that all must run smoothly – not to mention other servers looking after our Intranet and the normal mish-mash of servers that make up a small business’s back end.Depending on the season, with the number of boxes we manufacture in just an hour, a server failure could mean a plant shutdown, work stoppages or remote plant closures, and could cost us an amount bigger than I’d care to imagine!
- Our existing backup strategy involved rotating tapes and full backups to removable disks – yup, we were saddled with an older backup scheme that was getting worn and showing its age.Indeed, our server population was aging – most of our servers were between 5 & 10 years old, and as a result they were prone to major and minor failures.When there was a system failure, we were only backing up files, so that meant we had to recover the system first, building a replacement system from scratch, update the OS and install software, and then … Crossing our fingers as we restored files to the server from disk and tape.But the daily reality was it would take overnight to recover a lost file from tape – meaning we had to identify the tape the file was on and bring it in the next day from home.--If a Sequel server failed, the entire plant would be shut down while we tried to transition to working with pen and paper…The fallout from this was raising frustrations and costs – and the best we could do was file backups only – we had no provision for any kind of system-level recoveries.But there was hope on the horizon. I’d mentioned that our servers were all getting a little long in the tooth, and I’d just gotten the go ahead to virtualize our server environment.We were also looking at Business Continuity and we wanted a Disaster Recovery plan. Virtualization was going to help tie things together.But this plan was going to leave us with a mix of physical & virtual servers. That meant we needed to be able to back up both kinds of servers.
- By the time we started converting old servers to VM’s, we knew our existing backup software wasn’t up to the task.--We’d either have to pay for an expensive upgrade to our legacy software, or be left backing up just a few files to tape.--It all came to a head that we couldn’t ignore any more – we needed something that would look after our complete environment.
- I spent about a month looking for a solution that:A - Reduced recovery times of both applications and data from hours to minutes,B - Restored either back to physical or to VMware-based virtual machines,C - Replicated to a planned but not built remote DR site in case of a local site-wide disaster,D - Provided robust domain controller continuity. And finally, it had to back up both virtual and physical servers – being unable to do this (what I thought was a basic task) was a deal-breaker.I quickly discovered that my most basic of requirements - that is, backing up physical AND virtual machines was not going to be so simple to accomplish in a single package. There were the old timers that could only do physical server back ups, and the upstarts that figured everyone only used virtual servers.I sat through several webinars, downloaded various trial packages and checked them out, but hadn’t found anything yet that could do this. I really was about to give up, but through a search engine, up came the name AppAssure, and its website shouted out exactly what I was looking for!
- I must say, I raised my eyebrows at all the claims they made, as I couldn’t believe they were the only ones that could “do it all”.So I sat through webinar and was impressed, but I had to see for myself. I downloaded a demo and was convinced.The ROI and the advanced backup and recovery features made it not only a contender, but a no-brainer solution for us.My dream was about to become true - no more going home to get a tape just to recover a file. Well, not so much a dream, but I was happy to be able to recover files quickly!
- Dell loves to quantify things in customer case studies so I’ve agreed to this slide. But the most important thing is not numbers so much as peace of mind knowing that the problems we had prior to this are behind us.
- We achieved a major upgrade using two virtual AppAssure Core machines – one local and one at our disaster recovery siteThere are now virtual servers being replicated and on standby in case of failure in our 100% virtual DR infrastructure – making it easy to do “push button” failover to virtual. We can do rapid P2V and V2V migrations and DR testing without interrupting production systems. Our system now allows us very fast restores at any level: single file, email or even a complete server. One thing we don’t do though, is to tell users that we can restore individual emails or files lest they use us as their Recycle Bin.And of course – DR testing is nothing to be afraid of anymore!
- We’ve had a couple good examples of recovering from major failure.The first was a few years before I started here, and much before we got AppAssure, and it involved a crashed Exchange server. An outside consultant was called in and it was a 24 hour job to get something up and running just to get the email flowing again.The second example was a few months after AppAssure was installed when our primary domain controller crashed – it also handled file shares, DHCP, Print server, etc. The RAID backplane failed and the server was shut down. I’ve always been a hardware guy so my first instinct was to check out the server to see what was wrong. By the time I figured out there was no quick fix, it was back to my desk to bring up the AppAssure console to see what I could do. After a few mouse clicks I had a VMware host selected to place a virtual copy of the physical server on, and a few minutes later we were back in business. Although this was a heart stopping moment, once the new VM was running and it appeared to our users as if nothing had happened (other than the server “was down” for a short while, I marvelled at how easy and quickly what would have been a major disaster, was fixed. This was my first experience with having to recover a production server in a hurry. It went off without a hitch, and I then sat down and specked out a new Dell R515. Once it was delivered and ready to take over from the VM that replaced the old server, I restored the running VM to the new hardware.I can’t imagine the nightmare that would have ensued had I been stuck with minimally useable backup tapes and have to recreate a new server along with all the shares and user permissions, print drivers, DHCP scopes, etc. I’m sure that anyone that’s had a DC with many roles crash, knows it wouldn’t be a fun week trying to recover and restore everything. I think that AppAssure paid for itself in just this one major incident.Since then we’ve recovered plenty of “lost” emails and files for users generally within moments of their panicked phone call, and I can’t imagine going back in time and having to do this any other way!
- It’s really amazing how far backups have come over the last few decades. We’ve got entire servers being protected and replicated as often as every 15 minutes and others are backed up hourly or weekly, and all without any intervention. We went from rotating daily tapes that copied a few files and databases, to a system that copied the entire server in a very granular fashion. In the event of a system crash, no longer did we have to source a replacement server, wait for it to show up at the door, install the OS and patches, configure the server, install programs, and then hope that the data from tape was all intact.We’ve incorporated our backup system into a major component of our Business Continuity and Disaster Recovery plan that we hope we never have to use – but knowing it‘s ready should we need it. I don’t want to sound like I’m standing on the stage at an awards night, but I really am thankful that we’ve got AppAssure looking after our environment! Thank you!
