Testing Zetta: Storage Switzerland Reviews Our Cloud Backup Solution

Nick is Zetta's Corporate Reporter, and has been writing and telling stories about technology with blogs and social media since the days when the BBS reigned.


 
After a few weeks of testing our cloud backup service, Storage Switzerland published a review of Zetta DataProtect yesterday. In their words, the service is: “impressive – easy and reliable and certainly worthy of strong consideration.”
 
Let’s dig into more of their specific comments, and why they might be relevant to your organization’s data backup and recovery needs:
 

“One simple goal – get critical data offsite as simply and reliably as possible.”

 
Having an offsite copy of the really important data your organization generates everyday is an obvious advantage in scenarios ranging from a file server crash to a datacenter power failure. Tape backup solutions are not simple and consumer-grade online backup services are not reliable, but we’re happy to help achieve your “one simple goal.”
 

“Many cloud backup providers force the user to implement another piece of backup hardware.”

 
A unique feature of Zetta’s backup solution is that there is no appliance to buy, install, and manage in your datacenter. This means there’s no single point of failure like with an on-premise appliance. It also means lower TCO, since you never buy a unit – not to start with and not to “upgrade” with more storage later.
 

“A significant advantage for backup administrators needing to deploy across multiple offices or remote users.”

 
Another benefit of being appliance-free is that Zetta can backup all your remote offices easily with no extra fees. Even if an intern tried to backup all 5 seasons of Mad Men in HD she downloaded, it would be less than 300GB and barely move the needle on your monthly bill.
 

“A variety of methods to recover the data, the simplest being to mount the backup volume as a file system and drag back the files.”

 
The unique ability to recover files from a browser window is something that makes life so much easier when the inevitable data loss event occurs. All the files, directories, and databases are there and ready to use.
 

“Backend infrastructure more like that designed for primary storage and better able to handle growth.”

 
Zetta’s enterprise-grade data centers are SAS 70 Type II and SSAE 16 certified. These auditing standards are proof of how seriously we take data protection and availability. Consumer-grade services can’t and won’t offer this level of security.
 
The team at Storage Switzerland sees a lot of backup solutions, and they think Zetta is, “easy and reliable and certainly worthy of strong consideration.” Since the best way to consider a backup service is to try it out, we’re offering a 15-day trial here.

Great Cloud and Online Backup Solutions are Made, Not Born

Nick is Zetta's Corporate Reporter, and has been writing and telling stories about technology with blogs and social media since the days when the BBS reigned.

Best Online Backup
It was an honor today to find Zetta included in InfoStor’s 6 Great Cloud and Online Backup Solutions. The companies featured are a mix of consumer and business solutions and we’re thrilled to be compared with a legendary product like Symantec’s Backup Exec.
 
Of course, Zetta is unique on the list for being the only true enterprise-grade solution for SMEs. What makes Zetta’s DataProtect unique?
 
1. Enterprise-grade Performance, Redundancy, Security, and Support
 
We say “enterprise-grade” performance because of the speed of both backup and recovery you’re able to achieve using Zetta’s sub-file level technology and multi-threaded data transport over the internet. If speed is an important criteria for your organization, we challenge you to sign up for a free trial and test us against any other online backup provider.
 
2. Redundancy Across Disks, Nodes, and Datacenters
 
The DataProtect solution offers RAIN-6 (Redundant Array of Independent Nodes) redundancy technology, which stripes your data across independent computers keeping it safe whether there is a network, power supply, memory, or disk failure. RAIN gives rise to greater availability of the backup service, so it’s always there for backing up or restoring your data.
 
Zetta customers also have the option for their data to live in both our West Coast and East Coast datacenters.
 
3. Real Data Security
 
All Zetta customer data is encrypted at rest in our SAS70 Type II certified and SSAE 16 certified datacenters. This means compliance with many different industry data availability standards. Consumer-grade or white-labeled backup products are nowhere close.
 
Included in your monthly fee is 24×7 live support from our friendly engineers here in Sunnyvale, CA. They tend to solve issues really quickly then go back to building epic Star Wars Lego sets.
 
4. Appliance-Free
 
As Steve Jobs famously said, “If you see an appliance, they blew it.” Well, he said it about iPad competitors, but the meaning is true for enterprise cloud backup services.
 
5. Zetta Is Made For SME
 
If your organization has 2TB to 50TB of data to backup offsite then Zetta is the best choice you can make. Since Zetta is delivered as a managed service, there’s never a charge for the number of clients or plugins like SQL, Exchange, or VMware. And absolutely no bandwidth charges. Ever.

2 Totally Different Ways To Do SQL Server Backup & Recovery

Nick is Zetta's Corporate Reporter, and has been writing and telling stories about technology with blogs and social media since the days when the BBS reigned.

Database Backup Magic
This post is about how traditional database backup products work and how Zetta’s new SQL server backup feature, which is part of our DataProtect solution, does the job in a distinctly different way. Both the solution and this post were created because finding a database backup solution for a medium-sized organization is painful.
 

Database Backup Using “Full, Differential, and Log” Modes

 
Most traditional database backup products use “full, differential, and log” based backup modes. So, what do these terms mean?
 
A full backup is just what it implies — everything.
 
A log is essentially a list of the changes the database has made since the last full backup. If you have a full backup from, say, 4/1/12 and logs that cover 4/1/12 – 4/10/12, you can take the original backup, and replay the logs, bringing it current to the 4/10/12 version.
 
A differential is similar to a log based backup, but can be smaller and faster to recover in that it will have some amount of update coalescing, where if a given record (say a daily account balance) was updated over time the logs would contain each discrete value but the differential would contain only the latest version for that record.
 
With both of these backup types, it’s necessary to restore the original backup and the differential or log sets. This is what makes it less space and network efficient than a pure incremental backup.
 

Database Backup Using ZettaMirror with Sub-file Technology

 
Zetta’s lightweight software agent, called ZettaMirror, leverages sub-file technology to scan the database byte-for-byte to find database pages that have changed, and only transmit the pages that have changed up to the Zetta service.
 
While this is similar to an incremental backup, we actually restore the changes on our end, resulting in the most-recent backup being available and fully formed, ready for restore. Version history is always available via our space-efficient snapshots, going back in time.
 
The advantage is that it’s, “incremental forever,” handles any update type, and is the most efficient possible format for a restore.
 
Backup process of a Microsoft SQL database using ZettaMirror:
 
1) Connect to the database, inquire if it’s in simple recovery mode, or full recovery mode.
 
2) Using the .NET SQL Server Manager API, cause the database to de-stage any dirty pages out of memory onto disk, and use VSS to create a read-consistent version for the ZettaMirror Job.
 
3) Scan the pages across the VSS snapshot for changes, then transmit just the changes up to Zetta’s datacenter.
 
4) Create a named snapshot recovery point for this database on the Zetta volume.
 
5) If the database mode was full recovery mode and everything was successful, release the snapshot, and truncate the logs.
 
Because our methodology of always taking full backups, then using binary comparison to derive the change set, the use of Microsoft or other backup utilities will not cause ZettaMirror — unlike most other products — to produce a backup that can’t be restored.
 
As you can see, traditional database backup and Zetta’s DataProtect service featuring ZettaMirror are really 2 totally different ways to do SQL server backup and recovery. If you’re ready to try the Zetta way in your environment, you can start a trial here. If you have questions or want to learn more, feel free to give us a call or find out more about how it works.

Zetta DataProtect 3.0 Release – Here’s what the Backup & Recovery Industry is Saying

Nick is Zetta's Corporate Reporter, and has been writing and telling stories about technology with blogs and social media since the days when the BBS reigned.

Zetta DataProtect 3.0
Here at Zetta, we recently launched the 3.0 version of DataProtect, our enterprise-grade online backup and disaster recovery service. Some of the new features added in this release are:
 
- Support for new data types including MS SQL and Windows System State
- 10x performance increase using metadata cache and network data compression
- Platform support for Apple / Macintosh OS
- Easier operation with “Snap After Sync” snapshot trigger
 
As part of the launch we presented the new features to IT industry press and analysts. Some of their statements and reactions are below. Since these guys (and ladies) hear from almost every cloud service vendor at one time or another, they tend to have a pretty detailed understanding of the differences between solutions that sound similar on the surface. Here is some of what they said:
 
InformationWeek Logo
“In the event of a disaster, IT can mount a Web drive for direct access to the Zetta cloud. With system state backup, Zetta can rebuild the entire server to dissimilar hardware by reloading the operating system and applying the system state and user data files from the Zetta replica.” [Zetta Launches SMB Cloud Storage Platform]
 
Infostor Logo
“The company has developed a bandwidth-conserving code that cuts down on storage and network traffic. A lightweight agent is installed on a server or endpoint — DataProtect is a 100 percent software play, no hardware appliances here.” [Zetta.net Upgrades Cloud Backup Platform]
 
Network Computing Logo
“With the new version, Zetta.net now includes a feature called Snap After Sync, which gives users the ability to produce snapshots after the system has finished synchronizing.” [Zetta.net Cloud Backup & Recovery Service Refresh Offers 10X Better Performance]
 
Storage Strategies NOW Logo
“Zetta.net has transformed itself with version 3.0 and makes cloud data protection and disaster recovery feasible for the mid-market with compelling features, no capital expense and low, predictable operating expenses.” [Zetta.net 3.0 Provides Cloud Services For Data Protection and Disaster Recovery]
