Amazon S3 for Backup ≠ Disaster Recovery

Nick is Zetta's Chief Content Officer, and has been working with writing and social media teams to create digital content since the days when the BBS reigned.

Amazon S3 for backup
When Amazon S3 caused Netflix to go down in December, it highlighted 2 major problems with using Amazon S3 for backup: it’s not an integrated backup solution and doesn’t provide disaster recovery functionality.
 
Since adding additional layers of software to get complete backup and disaster recovery from S3 storage increases the cost by 8x – eliminating any perceived cost advantage – justifying S3 for backup is a difficult case to make.
 
Here’s why Amazon S3 for backup is a recipe for disaster (without recovery):
 
1. Reliability ≠ Enterprise-grade
 
The nature of backup is such that even small companies need enterprise-grade reliability, because if your backup data isn’t available when you need it, then the value of that backup is essentially reduced to zero.
 
Zetta’s Approach
 
The DataProtect 3-in-1 backup and recovery solution has a 100% recovery reliability. No customer has been unable to recover a file – that’s enterprise-grade reliability.

Online Server Backup Essentials: Successful Data Recovery

Nick is Zetta's Chief Content Officer, and has been working with writing and social media teams to create digital content since the days when the BBS reigned.

Online Server Backup - Data Recovery

Simple data recovery is better, as usual.


Backups aren’t really about backup, they’re about being able to recover – restore, really – data when you need to. So, just like with server backup, the fewer steps it takes to recover a file, the more likely the recovery is to be successful.
 
Conversely, the longer a recovery takes – hours instead of minutes, days instead of hours – the longer your business has to get by without essential data. Even a single file’s unavailability can be a showstopper. Delays of hours or days for disaster recovery can be, well, disastrous.
 

An ideal data recovery process:

 
1. Choose your recovery option – You want to be able to choose a different recovery method depending on the data loss or disaster scenario you’re facing. Zetta, for example, offers 3 recovery options: use the ZettaMirror software agent, a URL for browser-based recovery, or mount your backup volume just like a drive on your network.

Online Server Backup Performance and Value: The Merced College Story

Nick is Zetta's Chief Content Officer, and has been working with writing and social media teams to create digital content since the days when the BBS reigned.


California’s Merced College is using Zetta.net’s DataProtect for online server backup, to reduce backup windows, improve disaster recovery capabilities, and save a bunch of money.
 
The community college has over 17,000 students, 500 faculty, and 200 staff members. Their data center has grown to the point where tape backups weren’t an option, since they were taking all day. With 65 virtual servers, 30 physical servers, and 24TB in SAN storage, the IT team at Merced has a lot of data to backup, and a state requirement for disaster recovery.
 

“Disk-to-disk systems required a large investment that was beyond our budget.”

 
“We were dealing with the highly manual and time consuming process of storing tapes and tapes that were aging out,” says Don Peterson, director of information technology at Merced. “The system wasn’t meeting our needs, and traditional disk-to-disk systems required a large, outright investment that was simply beyond our budget. We soon began to evaluate our options for online server backup.”
 
Peterson started evaluating solutions that could eliminate the performance issues of working with tape. He also wanted a version history that would let his team go back at any point in time to recover files or restore machines that might go down.
 
Since Merced started using Zetta.net for online server backup and disaster recovery of 80% their server data, including virtual machines, SQL, and files – the college saved nearly $200,000 in reduced backup hardware and software costs as well as the cost of tapes.
 

“With Zetta.net’s online server backup we have immediate access to files when needed.”

 
“We’re saving an enormous amount of time compared to our old system which required many hours to manage, and restoring data could take days,” said Arlis Bortner, Merced’s Network Manager. “With Zetta.net, there’s very little to maintain and not only can we recover at any point time, we have almost immediate access to files when needed. We’re definitely getting a lot more value for much less cost.”

Protecting IT Assets From a Hurricane: A How To Guide

Nick is Zetta's Chief Content Officer, and has been working with writing and social media teams to create digital content since the days when the BBS reigned.

Protecting IT Assets From a Hurricane
When the local news starts reporting that a tropical storm or hurricane will make landfall near your town, do you know how to protect your company’s IT assets?
 
If you do, congrats! This post isn’t for you.
 
If not, here are some suggestions.
 
A Weather Warning Is When You Implement The Plan, Not Start It
 
A hurricane — or a similar event, like the June 29, 2012 “derecho” that slammed the eastern United States can strike without warning.
 
“In the greater Washington, D.C. area, where I live, the derecho was so rare and so violent that no one saw it coming — the emergency alert system only issued warnings half hour after the event had passed,” said technology analyst Wayne Rash, who wrote up the event and its impact on IT in eWeek. “I don’t think anyone could have planned for something this violent and this fast.”
 
An event like this doesn’t just take out power or connectivity. High winds and flood-level waters also damage entire buildings, while downed power lines and blocked roads can prevent or slow down repair activity – including the delivery of replacement hardware and appliances in the following days.
 
“The effects were devastating,” said Rash. “It took out just about every data center in the area — including Amazon. The power was out, as were phones, Internet, cell service even the water and 911 system went down.”
 
In other words: To be ready, you need to plan ahead — and also to be prepared for your best plans to not necessarily be good enough.
 
Here’s some a starting point for what SMBs and remote and branch offices can be do to protect IT assets.
 
How To Prepare
 
Preparing for a weather event, like any project, involves a mix of assessment, plans and lists, policies and procedures, gear, training and practice.
 
Know Your Location:
 
What events are you vulnerable to? Are you on a flood plain? How high above ground level is your IT gear and cabling? How much weight or wind can your building’s roof, windows, and walls sustain? Are there large trees that could fall on your building, and if so, what’s the condition of their root system?
 
Inventory and Prioritize Your IT Assets:
 
Getting an inventory is easy — and you should already have one, for accounting and insurance documentation.
 
Next step: Prioritize which applications you would like to keep up, if possible, and which hardware you are most concerned about protecting. (Almost all hardware can be replaced — but some might not be quickly available, or not in the same model and configuration.)
 
For now we’ll assume you’ve already protected your data with offsite backup.
 
For many SMBs and others, points out Beth Cohen, Senior Architect at Cloud Technology Partners, this won’t be a problem. “Many SMBs don’t have local servers any more, and are using cloud-based services instead. For them, their primary assets will be client machines — desktops and laptops.”
 
For companies using local servers, “See if you can move them to the cloud, at least as a failover option,” suggests Cohen.
 
Also, urges Cohen, “Make sure all your employees have methods of accessing systems for telecommuting access.”
 
When you do get a weather warning, “Get system images, turn them off, unplug their power and network cables, bag them to make them as watertight as possible, and put them as high above the floor as possible so they don’t get flooded,” says Cohen.
 
Additionally, look for ways to remotely access your data for administration and management. And have some spare systems, like a laptop or two, so you don’t have to wait for replacements — which can take longer when the roads are out and public safety remains the top priority.
 
Data Recovery Is The Real Goal
 
“Barring specialty stuff, hardware is a commodity, which can be insured and replaced,” Cohen points out. Unless you need to be able to operate locally — for example, if you provide medical services — planning for disaster recovery through other locations makes the most sense. For example, if you’re in Orlando with backup systems in Atlanta, both sites are unlikely to be impacted by the same event.”
 
So, while it’s worth identifying physical assets that should be protected, pay attention to preserving or restoring the business services these assets provide. Hardware can be replaced; downtime can’t.
 
You’ll also want to prepare and plan for what to do during a major event — and afterwards.
 
For protecting data from major storms Zetta.net offers a 3-in-1 offsite backup, disaster recovery, and archiving solution that starts at $199 a month.

Affordable Disaster Recovery: Compliance in the Cloud

Nick is Zetta's Chief Content Officer, and has been working with writing and social media teams to create digital content since the days when the BBS reigned.

Get Your Compliance Ducks in a row
The primary reason to have a data disaster recovery strategy is to ensure that data is protected, preserved, and recoverable, in the event something happens.
 
But those aren’t the only reasons for backups. Think disaster recovery compliance.
 

Are You Subject to Disaster Recovery Compliance Regulation?

 
Depending on what industry your company is in or serves, you may be subject to government and/or industry regulations. Disaster recovery compliance includes ensuring data protection and availability – even after a site-level data disaster event.
 
Disaster recovery compliance regulations that affect backup:
 
HIPAA (Health Insurance Portability and Accountability Act) for medical organizations
HITECH (Health Information Technology for Economic and Clinical Health Act)
SOX (Sarbanes–Oxley Act of 2002) for financial institutions and practices
FERPA (Family Educational Rights and Privacy Act), for educational institutions
 
For example, the Health and Human Services department says about HIPAA, “covered entities must: Ensure the confidentiality, integrity, and availability of all e-PHI [Protected Health Information] they create, receive, maintain or transmit.”
 
This means that, according to Sandra Nutten and Chris Mansueti from the American Health Information Management Association (AHIMA), “At a base level, the proper policies, processes, and technologies must be put in place to ensure that electronic PHI is backed up regularly and can be restored.
 
Because an “event” can make onsite data, or even an entire data center unavailable, it’s the job of the offsite backup to satisfy these requirements.
 

Encryption and Geography are the keys to compliance

 
StorageIO Group founder and senior analyst Greg Schulz has this advice for compliance-meeting features to look for in off-site backups:
 

“Make sure they are source-side encrypted — that backups are encrypted before they leave your computer or building. Some services only encrypt when the data arrives.”

 
Also, says Schulz, “When you are sending your backup data, do you know where it’s going, and can you control the destinations? Are you assured that your data isn’t leaving the state or country, or not going to specific other countries? Is this explicitly stated in the user agreement, or your SLA or SLO (Service Level Objective) requirements?”
 
It’s also important to understand which disaster recovery compliance requirements a storage solution can’t address, for example, the “automatic logoff” required by HIPAA, which is outside the storage layer, and therefore a client-device concern.
 

Using the offsite backup to get compliant, save money

 
For backup and recovery, many compliance requirements are identical to features you have – or could get – from the backup solution you’re already using to protect business data.
 
Zetta, for example, encrypts data both in flight and at rest, and has regular audits of operating controls like SSAE-16 (the replacement auditing standard for SAS-70 Type 2) and SysTrust controls. These will support your company’s implementation of HIPAA or FERPA controls.
 
If you have enough of a features match, this may mean that the backup you are using for business purposes may also be able to serve as your compliance-meeting backup(s), letting you, for a change, remove some items from your IT budget.
 
So, if your organization is subject to HIPAA, SOX or another disaster recovery compliance requirement, see if your data-protection backup can also serve as a compliant backup.
 
The odds are good that even if this means spending more on backup, the total will be less than having to do multiple redundant backups to get compliant with both your CIO and Uncle Sam.
