    be greater with more comparisons in addition the size of the index will be larger with smaller chunks which could result in decreased backup performance Performance can also be impacted because the chunks have to be reassembled to recover the data Byte level reduction is a byte by byte comparison of new files and previously stored files While this method is the only one that guarantees full redundancy elimination the performance penalty could be high Some vendors have taken other approaches A few concentrate on understanding the format of the backup stream and evaluating duplication with this content awareness Where and when to dedupe The work of data dedupe can be performed at one or more places between the data source and the target storage destination Dedupe occurring at the app or file server level before the backup data is transmitted across the network is referred to as client side deduplication a must have if bandwidth reduction is important Alternatively dedupe of the backup stream can happen at the backup server which can be referred to as proxy deduplication or on the target device which is called target based deduplication Deduplication can be timed to occur before data is written to the disk target inline processing or after data is written to the disk target post processing Post process deduplication will write the backup image to a disk cache before starting to dedupe This lets the backup complete at full disk performance Post process dedupe requires disk cache capacity sized for the backup data that s not deduplicated plus the additional capacity to store deduped data The size of the cache depends on whether the dedupe process waits for the entire backup job to complete before starting deduplication or if it starts to deduplicate data as it s written and more importantly when the deduplication process releases storage space Inline dedupe could negatively impact backup performance when the app uses a fingerprint database that grows over time Inline approaches inspect and dedupe data on the way to the disk target Performance degradation depends on several factors including the method of fingerprinting granularity of dedupe where the inline processing occurs network performance how the dedupe technology workload is distributed and more Hardware versus software deduplication Many of today s most popular hardware based approaches may solve the immediate problem of reducing data in disk to disk backup environments but they mask the issues that will arise as the environment expands and evolves The issue is software versus hardware On the hardware side purpose built appliances offer faster deployments integrating with existing backup software and providing a plug and play experience The compromise There are limitations when it comes to flexibility and scalability Additional appliances may need to be added as demand for capacity increases and the resulting appliance sprawl not only adds management complexity and overhead but may limit deduplication to each individual appliance With software approaches disk capacity may be more flexible Disk storage is virtualised appearing as a large

  • How to buy data deduplication
    offices as well as an efficient data protection alternative for server virtualisation environments However the integration of acquired deduplication products by EMC Avamar and Symantec Corp PureDisk with NetWorker and Veritas NetBackup respectively as well as recent introductions of native dedupe by CA CommVault and IBM have a lot of IT organisations wondering which is the best implementation of deduplication hardware or software Bottom line It s not a one size fits all scenario Cost performance scalability and the deduplication domain are just a few of the considerations when evaluating deduplication in the backup process to determine whether a backup application s built in dedupe capability or a feature built into a backup storage system will best serve your environment Here are some other considerations when choosing a data deduplication product Cost Presumably an investment made in technology that can reduce storage capacity requirements by a factor of 20 will be easily justified Is there an added fee to enable the feature whether it s a backup app capability or an add on feature in a hardware device Is an upgrade to a higher version or model required Even if deduplication is standard in the product hardware or software what other cost implications are there for implementing it e g will it require additional network server or storage resources Data deduplication performance Deduplication comes in all shapes and sizes as backup workloads have different requirements Deduplication may be mixed and matched taking advantage of features of both software and hardware products Source side data dedupe in backup software may make the most sense for remote systems because it delivers greater network efficiency while target based dedupe approaches may make more sense for workloads with the most stringent data backup windows Product scalability While deduplication should mitigate the need to expand storage capacity the impact of growth on the dedupe environment should be thought through You need to determine how easy or difficult it is to expand the deployed product and if expansion will introduce silos of storage and thereby limit deduplication and increase management And does scaling require a forklift upgrade or can it be achieved more seamlessly Deduplication domain You also need to consider the scope of the deduplication effort Will your dedupe effort be limited to the confines of a single container whether it s logical or physical or are your goals broader Such a wealth of deduplication options provides ample choices but it can also lead to some confusion Vendors have the opportunity to educate users about deduplication technology in general and specifically how their own solutions approach the task And you need to understand your backup environment and requirements before short listing solutions Vet the vendors and their products check their references and most importantly test the products using your own data over several backup cycles This was first published in June 2009 Dig Deeper on Data deduplication and reduction All News Problem Solve Week in review Hitachi s unified storage system will EMC buy XtremIO

  • How to understand deduplication ratios
    the frequency of full backups versus incremental or differential backups the higher the deduplication potential since data will be redundant from day to day Data retention settings the longer data is retained on disk the greater the opportunity for the deduplication engine to find redundancy Data type some data is inherently more prone to duplicates than others It s more reasonable to expect higher deduplication ratios if the environment contains primarily Windows servers with similar files or VMware virtual machines Rate of change the smaller the rate of change the higher the likelihood of finding duplicate data Deduplication domain the wider the scope of the inspection and comparison process the higher the likelihood of detecting duplicates Local deduplication refers to the examination of redundancy at the local resource while global deduplication refers to inspecting data across multiple sources to locate and eliminate duplicates For example a daily full backup of data changing at a rate of 1 or less that is retained for 30 backups has 99 of every backup duplicated After 30 days the ratio could reach 30 1 If on the other hand weekly backups were retained for a month then the ratio would reach only 4 1 Deduplication rates can be confusing Some vendors express reduction as a percentage of savings instead of a ratio If a vendor cites a 50 capacity savings it s equivalent to a 2 1 deduplication ratio A ratio of 10 1 is the same as 90 savings That means that 10 TB of data can be backed up to 1 TB of physical storage capacity A 20 1 ratio increases the savings by only 5 to 95 Evaulating a dedupe product When evaluating data deduplication it s important to trial vendors products in your environment with your own data over several backup cycles to determine a product s impact on your backup recovery environment The focus of selecting a product should be less on reduction ratios as a decision factor ESG research ESG Research Report Data Protection Market Trends January 2008 found that not surprisingly the cost of the deduplication solution was the most frequently cited factor although savings garnered from capacity reduction often overcome financial objections to deploying deduplication Otherwise the survey data suggests that ease of deployment and ease of use as well as the impact on backup recovery performance were important considerations more so than technical implementations such as the deduplication ratio This was first published in May 2009 Dig Deeper on Data deduplication and reduction All News Problem Solve Week in review Hitachi s unified storage system will EMC buy XtremIO Legal Aid NSW picks EMC CDP for SAN DR upgrade Symantec Australia leaves its NAS offshore for now Simpana 9 on sale in Q3 adds source based de duplication Load More View All Week in review Hitachi s unified storage system will EMC buy XtremIO Legal Aid NSW picks EMC CDP for SAN DR upgrade Symantec Australia leaves its NAS offshore for now Simpana 9 on

  • Western Digital undisputed King of disks, vanquishing Seagate, after Hitachi GST buy
    more useful than that PR blather was offered by analyst firm iSuppli which said through analyst Fang Zhang that the deal gets WDC into the enterprise a market where it currently has a very thin presence indeed WDC currently is only a marginal player in the enterprise HDD market with nearly all of its sales going instead to the market for consumer drives an area that includes products like desktop and mobile PCs set top boxes and video game consoles Zhang notes in his own press release Of all of the major HDD suppliers Western Digital in the fourth quarter of 2010 had the smallest share of any company s total shipments going to the enterprise segment at less than 1 percent In comparison 65 percent of Seagate s HDD shipments and 27 percent of Hitachi GST s shipments went to the enterprise market Zhang also notes that the combination of WDC and Hitachi GST is comfortably the largest disk vendor on the planet With the purchase WDC will claim 49 6 percent share of global Hard Disk Drive HDD unit shipments based on fourth quarter totals compared to 29 4 percent for Seagate his press release says before hitting CTRL B to state This will give WDC a lead of 20 2 percentage points over Seagate up from a mere 2 points without the acquisition This makes WDC the undisputed king of disk drive shipments even if Seagate gets most of the high margin cream that comes from enterprise sales Seagate s blogs and media centre are silent on the acquisition but of course the enterprise market is rather more lucrative than its consumer cousin WDC s arrival in the space gives it the chance to chase higher margins and volumes and will surely make Seagate uncomfortable at the very least Market reaction to the acquisition has been positive WDC shares jumped after the deal was announced Seagate s did likewise Storage bloggers are to date largely quiet on the acquisition save for Nigel Poulton who opines that while enterprise business has high margins it probably also has high R D costs He therefore wonders will WD be up for the fight with Seagate IBM and Hitachi clearly weren t So what happens if WD decide not to compete in this space If Seagate became the sole supplier in the enterprise space they could effectively charge whatever they want Competition drives cost down Competition also drives innovation so where would the drive for innovation come from if this were to happen Dig Deeper on Disk based backup All News Problem Solve Mean time between failure vs load unload cycles How to use Symantec NetBackup OpenStorage for disk to disk backup and recovery Importer dumps tape for Acronis backup Law firm ditches tape for the cloud Load More View All How to use Symantec NetBackup OpenStorage for disk to disk backup and recovery Importer dumps tape for Acronis backup Law firm ditches tape for the cloud Australian Catholic University plans
