Business needVillage Bank experienced laborious tape backup schedules, manual rotation of tapes, and a growing backup window due to ever-increasing data, in addition to anunacceptable 50% failure rate of their backup solution.SolutionsWith state-of-the-art disk imaging solution and application-aware system notification, Village Bank is able to recover its data easily and reliably, implementing a bank-wide disaster recovery process.Application areas• Disaster Recovery • Storage Solutions • VirtualizationBenefits• Five (5) minute recovery time • 140% ROI• Reliable backup and disaster recovery processes• Intuitive user interface for ease of use• Comprehensive disaster planning abilityHardware• Dell™ PowerEdge 950, 1800, R710, and R210 servers• Dell EqualLogic PS4000 SAN“Our DR strategy has completely changed with Dell AppAssure because now we have the time to focus on the future and meet our goal of doing replication off-site.”Bob Thomas, Vice President of Information TechnologyVillage Bank overcomes 50% failure rate with backup exec withcontinuous disk imaging solution, gaining a 140% ROI in the processVillage Bank IT environment includes250+ mail boxes, 4 SQL servers, 25 Windows file servers, 9 virtualized servers running Hyper-V, and upwards of 4 TB of data. “We’re a midsized bank which also owns a mortgage company,” explains Thomas. “We have 18 locations around the Richmond area and a staff size of about 230 people. Our infrastructure includes mortgage loan origination applications, Fiserve’s bank imaging system, and client account opening software platforms all running on our SQL servers. Plus we’rea service bureau bank, which means we work with Fiserve, who does the heavy lifting of core processing of accounts payable, account management, and so on. So there’s a lot going on at any one time. We were using Symantec Backup Exec12 and our backup jobs were continually failing, leading to questionable recovery scenarios.”Thomas estimates that his three-person IT team had to deal with unacceptable failure rates of up to 50%—regularly.“We would do a daily backup which ran three to six hours a night, and then a full backup on Friday, plus a monthly,” says Thomas. “We don’t have a staff to comein on Saturday, so we’d get the backup on Monday and about 50% of the time, find an error. There wasn’t much we could do about it because we couldn’t afford to rerun the backup, so we’d just note we had had a failure and hope we wouldn’t need to recover anything, because if something failed, we’d be out two weeks of data.We thought about redoing the backup schedule, and looked at another tape mechanism, but it was just too expensive for us. We’d call Symantec on the failures, but they could only recommend a patch or have us waiting for the next version.”This nightmare scenario was made all the worse by the fact that the bank had grown so much in the last couple of years that it was expanding faster than Backup Exec’s solution could keep up with it. The backup jobs began to take longer and longer, while the increasing data took up more and more tape.“The failing backup jobs put the company at risk when a recovery is required,” says Thomas emphatically. “Since the number of tapes and time required to do a full backup was increasing, we knew thatwe needed a more secure and reliableIt’s one thing for a bank to have to deal with laborious tapebackup schedules, manual rotation of tapes, and a growingbackup window due to ever-increasing data. It’s quite anotherwhen the best you could hope for each month was a 50%success rate for a good backup. But that was precisely thesituation that Bob Thomas, Vice President of InformationTechnology at Village Bank, faced month after month.23process for the bank. Not only that, we were committed to developing a comprehensive disaster recovery (DR)process, and we couldn’t do that with what we were using.”15 minutes to a full server restore.Village Bank had its mission critical servers set up on separate tape apparatuses and kept close tabs on it for failure, yet all its other servers were still vulnerable. “If we had a disaster, the mission critical servers were ok,” notes Thomas, “But the mail server and others were very vulnerable. We were looking at 2-3 weeks of recovery time if there was a disaster, because we had to make choices about what could come back online when needed.”“We spent a lot of time reviewing theproducts that are out there,” notes Thomas. “Since we run n-Central, a monitoring system from n-Able, we did a trial on the solution they suggested. But just as we were about to make a decision, we had a tape machine failure and I decided that was it. I didn’t want to reinvest in tape any longer. It was just too expensive for repeat problems.”Thomas’s team came across Dell AppAssure and did a trial. Within 15minutes, Village Bank’s servers were all up and protected by in a test mode. Thomas chose Dell AppAssure.“Our backups are running much quicker and the time to recovery is cut from hours and days to just minutes,” says Thomas. “Not only that, but the ability to go into Exchange store and restore one email with Dell AppAssure has been eye opening.”You can’t argue with the numbers: a 140% ROI.Thomas can easily make before and after comparisons:Recover in minutes.“Before Dell AppAssure, if a file was lost or accidentally deleted, we would have to request the tape from an offsite storage facility and wait for the courier to deliver it.This meant that it wasn’t at our data center until the next day. Once we received the tape we would have to run the restore job, which could take another hour or more. Now this process literally takes only minutes. This is like night and day.”Server-level recovery.“While we haven’t had a complete failure—I’m new to the virtualized world—we did experience a glitch with a host server having disk space taken up as we were virtualizing. Luckily we had some DellAppAssure image snaps ready and available. I blew up the virtual image and restored from the last good recovery point. This took less than an hour and I did it from my house in the evening. I didn’t have to be in the office swapping tapes like before.”More storage capacity.“Based on the current readings of our Dell AppAssure console, we are at 27.19x storage savings. But this isn’t quite accurate, because now we’re able to back up much more data than we were before! Now it’s not just our one mission critical SQL server, but all our machines!”Great return on investment.“Calculations are showing a total savings of $88,859 with a 140% ROI. But that’s not what’s so important to me. I said to my boss, ‘Here’s the cost to stay in 1980s technology now that our tape drive has failed, and we’re in the 21st century.’ The ROI is just a bonus.”Increased staff productivity.“We now have time to think about other things—we can better plan, execution goes a lot easier, and we’re not always fighting a fire. We no longer think about backups because Dell AppAssure has freed up staff time by eliminating the manual process of regularly logging, couriering, and reviewing tapes, which took about 1-2 hours a day.” Village Bank can now feel confident that its data is protected as it looks to the future. “Dell AppAssure has completely changedour DR strategy because we have thetime to focus on the future,” says Thomas. Village Bank can now meet its goal of doing replication off-site, which is what is up next on Thomas’s team’s plate.Recently, a user deleted a large number of folders, representing about 15GB of data, off the Bank’s shared drive. With Dell AppAssure, Thomas recovered the data in less than five (5) minutes. The bottom line,” says Thomas, “is that Dell AppAssure lives up to the hype—the literature is point on. I would encourage anyone who is looking for a good backup and disaster solution to take those words to heart. Dell AppAssure works – it does what it says it does.”View all Dell case studies at /casestudiesAvailability and terms of Dell Services vary by region.
