A couple of months ago, my co-blogger Tory Skyers wrote a post questioning the impact of data deduplication on evidence preservation and chain of custody best practices for e-discovery data.
It’s a question many users are asking, apparently, as “Mr. W. Backup”, GlassHouse Technologies vice president of data protection services W. Curtis Preston recently addressed it on his Mr. Backup Blog. First, Curtis brings up the fact that if today’s legal standards for electronic evidence considered dedupe/compression a change in the data rendering it inadmissable, data from tapes (naturally compressed) wouldn’t be admissible either.
But Curtis also brings up another interesting point, and this is where I think the e-discovery waters have been muddied by everyone and their brother positioning products for that space. He writes:
You have to address the entire chain of custody. Let me give an example. If every email that is sent or received by an email system is immediately archived and stored in an archiving system that can demonstrated for anyone concerned when/where an email came from and how long it has been stored, you could use that system to build a non-repudiatable source of data that could be used in legal proceedings. (It’s not just about the software, of course, as you have to address access and all other kinds of issues, but that would be a start.) BUT, IMHO, non-repudiation requirements have much more to do with proving chain of custody than they do with the content of the data, and dedupe systems are just as good at proving that as any other storage system — [in other words] they don’t. It’s usually up to the system that put the data in there and took it out.
I think Preston raises many good points, but this doesn’t negate some of the points Skyers also raised. Among the biggest: “Are we sure our legislators understand the differences between a zip (lossless) and JPEG (lossy) compression?…The answer to these questions, while second nature for us technology folks, may not so second nature for the people deciding court cases.”
If IT pros are mulling and chewing over this question, you can be sure lawyers are, too. And out of the pool of citizens that could make up a jury of your peers, how many would immediately understand Preston’s paragraph above?
Just as its MAID technology did, Copan’s energy-savings deal with Pacific Gas & Electric that began late last year is expanding.
PG&E offers rebates for customers who use storage systems it has certified as energy-efficient. The utility started last year with Copan’s Revolution systems and last week qualified 3PAR’s InServ systems.
An initiative called Conserve IT revealed today by storage research group Wikibon and seven storage vendors looks to bring more vendors and more technologies into the PG&E program, as well as help other utilities offer similar programs. Wikibon is measuring the green-friendliness of technologies such as MAID, flash, thin provisioning and virtualization.
The first vendors to sign on are 3PAR, Compellent, DataDirect Networks, EMC, Hitachi Data Systems, Nexsan and Xiotech.
Wikibon founder and principal contributor David Vellante said his group will validate the baseline for energy efficiency, test products, write reports and submit them to PG&E.
“We bring in the last mile,” Vellante said. “We do the dirty work about really understanding why these products are more energy-efficient than some baseline. We determine where does that baseline come in and who measures this.”
Vellante said Wikibon is talking to utilities companies in Texas, California, New Jersey, Minnesota and Canada and he expects to add others to the list. Other technologies will likely be targeted too, such as data deduplication.
He said Wikibon and Conserve IT has no formal deal with PG&E, and vendors can qualify their technologies without its help. But the group has already helped 3PAR certify InServ. Vellante said along with storage companies, he is talking to software, server and communications firms. “We feel we can do this more quickly and efficiently than anybody right now, other than PG&E,” he said.
The program comes at the right time, as hype over green computing is being replaced by people actually looking to do something about it — even if it is more to save money than to save the environment in many cases.
NetApp’s gift of a T-shirt the other day made me think about all the other s.w.a.g. I’ve collected during my time in the storage industry – I’ve become something of a collector of odd trade-show tchotchkes. And I realized when I looked at the items I’ve kept, my desk has become a personal museum of now-defunct or acquired companies. So I thought a brief tour of my collection might be a fun Friday post.
Here are some of the things I’ve accumulated: Continued »
According to Symantec’s earnings call last night, updates to NetBackup announced at Symantec Vision in June helped keep its storage business strong this quarter. Storage and services revenue increased 20% year over year to $616 million, which COO Enrique Salem attributed in part to new NetBackup features such as continuous data protection (CDP) and integration with PureDisk data deduplication.
The ability to offer customers one throat to choke for storage management, archiving and backup has also paid off, according to Salem, as the sales force focused on selling across product groups. Enterprise Vault sales grew 30% year over year, and the product enjoyed some good publicity this quarter with selection to various analyst product rating lists and customers raving at Vision about its features. The Storage Foundation product line also “posted its best results in years,” according to Symantec, though numbers weren’t given.
Symantec has had a rocky time of it in the recent past, especially over the last year, following frequent managment shifts and its market share slipped in IDC quarterly tracker reports on the storage software market. As recently as last quarter, there was speculation that Symantec would sell off its storage business units.
But during last quarter’s earnings call, Symantec also reported good growth for its storage business units. Email archiving, backup, and storage management were among the product segments that posted double-digit year over year growth for Symantec’s fiscal fourth quarter.
There’s one dark cloud still threatening to rain on Symantec’s parade, however — its sales channel. Earlier this month it was reported that Symantec would be going direct with its largest customers, a report that was later contradicted by top Symantec channel executives.
That hasn’t stopped unrest among channel partners whose feathers were ruffled by the original report, and it hasn’t stopped Symantec competitors from swooping in to try to take advantage of the confusion. Following last night’s earnings call, skepticism over Symantec’s “conflicting channel messages” seemed to have spread to financial analysts, as well. According to a note to investors sent out by TBR:
Although Symantec defends the announcement by explaining that its strategy actually hasn’t changed, but that it only made its customers aware of the option to go direct, TBR believes the damage has already been done in the partner community. Symantec competitors wasted no time in stepping in to try to lure Symantec partners away, as Trend Micro and other smaller players made bids for Symantec’s partners by pushing their own channel programs during the confusion. Although the strategy would give Symantec more control over cross selling its portfolio in its largest accounts and potentially improve margins, TBR does not expect the change to make a big impact on either metric. However, greater involvement in large accounts from the direct sales force will give Symantec more control over cross selling products across its portfolio to drive new license revenue in existing accounts.
Just about all data deduplication vendors make claims about the dedupe ratios their systems provide, with the caveat that the ratios vary by data type and backup frequency.
Sepaton today says it’s willing to guarantee its ratio for Exchange. The VTL vendor said if customers don’t get a 40:1 ratio with its DeltaStor dedupe software in 30 days, it will throw in a free disk shelf with at least 7.5 TB of capacity – a $50,000-plus value.
There are some conditions. First, the customer must use Symantec NetBackup for now, because that’s the only backup software DeltaStor supports. And the customer must do daily full backups, which result in better reduction than incremental backups. The guarantee is part of what Sepaton calls a FastStart Deduplication Package for Symantec NetBackup, consisting of an S2100-ES2 library with 20 TB and DeltaStor.
Analysts who closely follow the dedupe market say Sepaton deserves credit for making the guarantee, but isn’t exactly sticking its neck out. Because Exchange includes a lot of messages sent to multiple recipients with attachments, it tends to have a great deal of duplicated data that can be reduced.
“To guarantee anything takes guts,” Arun Taneja of the Taneja Group said. “It’s a good marketing strategy for them to set the trend and draw a line in the sand. But for full backups for email for 30 days, 40:1 is very achievable. So I would say it’s not a very large risk.”
Glasshouse backup guru Curtis Preston agrees. “I think it’s a great idea and I doubt they would have done it if they hadn’t already done a lot of testing to verify they actually can get more than 40:1 in most Exchange environments,” he said. “There is a lot of duplicate data in Exchange.”
Sepaton director of product management Jim Shocrylas said the 20 TB system would give a customer with 4 TB of daily full backups a retention period of about half a year. He said the guarantee applies to full backups because Microsoft’s best practice recommendation for backing up Exchange is daily fulls.
“This is first of a number of guarantees we’ll be coming up with for specific data,” Shocrylas said. “Others will follow.”
NetApp has struck back in the ongoing catfight with EMC - this time in the form of a T-shirt.
According to an announcement made this morning, NetApp’s V-Series gateways can now dedupe storage from HDS, HP, Fujitsu, and 3PAR, among others, but with this promotion, they’ve chosen to focus on you-know-who:
Now I’m waiting for EMC to send me a “NETAPP SUCKS” coffee mug.
In an economic downturn, not everybody makes it through in one piece. Though the storage market has fared better than many (apparently the list of things in life you can count on has been expanded to three: death, taxes and data growth), it isn’t without its casualties. Ciprico and Agami are the two latest.
The Minneapolis-Star Tribune reports that storage controller startup Ciprico has filed for Chapter 11 bankruptcy. According to an analyst quoted in the Star-Tribune story, “Ciprico spent too much cash last year building a sales force to sell a radical new disk storage product that consisted only of software rather than a computer device…Ciprico had the funds and burned them up too quickly.”
Ciprico reported a loss of $3 million on $2 million in revenue for the first quarter of this year, then laid off 30 percent of its staff in March. Ciprico CEO Steven Merrifield told the Star-Tribune he hopes to sell off the company’s technology
Poor judgment in the spending department may have been a factor, but Storagezilla also attributes the downfall of smaller companies to the general economic climate. “During a downturn the bigger players get bigger while the smaller ones collapse or are picked off via acquisition,” he wrote – in the midst of reporting that NAS vendor Agami has folded.
I since received confirmation from an Agami source that it has indeed gone out of business, although its web site and phone system are still functioning. In today’s economic climate, it wouldn’t be surprising if more “on the bubble” storage companies bite the dust.
The turnover that often occurs when a large company buys a smaller one has begun at Dell/EqualLogic, about seven months after Dell closed its $1.4 billion acquistion of the iSCSI SAN vendor. The most visible of these departures was delivered via vlog by Inside IT blogger and Dell/EQL evangelist Marc Farley, who gave his reason for leaving as “I’m not much of a big-company guy. I don’t know if I’m allergic to them, or what.” Farley said he’d be going to work for a smaller storage vendor, but didn’t specify which.
This is similar to what I heard recently from Roman Kichorowsky, former director of PR for EqualLogic, whose name is on a Dell press release as recently as July 10 but who has now moved on to FalconStor.
It’s not unusual for employees to leave in these kind of acquisitions. There are real cultural differences with almost every merger, and you’ll always find people who smile big until the press coverage dies down, wait for options to vest, and then get out.
But Dell’s retention of EqualLogic’s service and support staff as well as channel partners were major concerns for EqualLogic customers after the acquisition. The departure of PR and marketing people almost surely won’t affect the customers. But it’s worth keeping an eye on who else chooses to exit.
Atempo has been busy lately working its archiving story. Over the last six weeks, the backup software vendor has released an email archiving application and forged partnerships with Nexsan, Nirvana and – as of today – Permabit.
Atempo and Permabit say they’ve completed interoperability testing of the Atempo Digital Archive (ADA) file archiving software solution with the Permabit Enterprise Archive disk-based storage system.
While such partnerships have become common for smaller storage vendors looking to take on larger players, a partner has to bring something to the table to make it worthwhile. For Permabit, Atempo adds support for user-initiated (along with admin-initiated) archiving and the ability to archive Mac and Windows files in the same repository.
“Now shops can have admins set policies as well as user-set retention rules, and they don’t have to step all over each other,” Permabit director of product marketing Louis Imershein said.
Imershein said while Permabit’s customers tend to be enterprises, most of them have Macs somewhere — usually in the art or graphics departments. He said ADA makes it easier to manage archives regardless of what type of applications are used. “It’s a nice way to re-direct users to the archive without having to go through a filter drive, they can make a direct hop,” he said. “In enterprises, you wonder how people can do without that.”
Analyst George Crump of Storage Switzerland agrees that Mac support is becoming important in large companies. “I’m seeing an uptick in use of Macintoshes, even in the enterprise,” he said. Crump is also seeing a need for simpler interfaces such as ADA’s in archiving. “Many applications are too heavy — for lack of a better word — and they bring more to the table than needed,” he said. “Disk-based archiving simplifies archiving compared to tape and optical archiving. But there wasn’t a simpler app to take advantage of the simpler interface.”
But with no shortage of archiving products in the market now, getting people to take a look at their simple products will be the hard part for little guys like Atempo and Permabit.
Last week I noted that EDS shareholders had filed suit to delay the closing of HP’s acquisition of the IT services company. The Wall Street Journal has since reported that HP and EDS will settle with those shareholders. As part of the settlement agreement, HP and EDS will delay the merger until Aug. 18. That allows investors to reap an additional 5 cent-per-share dividend. The companies have also agreed to turn over more information about the structure of the deal requested by shareholders.
