<< Back to Index Business benefits of data deduplicationġ) Substantial reduction in data center capital and operating costs by lowering the requirements for equipment, power, cooling and floor space.Ģ) Recently, tapes have been replaced by disks as secondary storage media. Vendors are now augmenting their existing solutions or offering new ones to apply deduplication to primary storage systems as well. Virtual environments also benefit quite a bit as marginally separate system files of different virtual machines can easily be combined into a single storage space.Įffectiveness of deduplication solutions is measured in terms of the de-dupe ratio as follows:ĭe-dupe ratio = Total data sent by the application(s) to the storage system/Total ‘raw’ storage capacity of the storage systemĭeduplication solutions have been applied mainly to secondary storage systems in the past. Data deduplication helps address this by preventing duplicate data from being part of the equation.īackup applications benefit from deduplication as most of the data in a given backup doesn’t change from the previous backup of an existing file system. The greater the amount of data in an organization, the more difficult it is to meet RTO (recovery time objectives) and RPO (recovery point objectives). Multiple copies of data in secondary storage systems are the biggest source of this type of data. Data deduplication vendors and their offeringsĭuplicate data results in increased storage, backup and retrieval time and costs.Business benefits of data deduplication.
#ES DEDUPLICATOR WINDOWS#
Image Backups only work with a Windows client and can only be done with volumes which are formatted with NTFS.Download this data deduplication tool kit for free! UrBackup Client runs on Linux, Windows and FreeBSD. UrBackup can also use btrfs in a way that makes deduplication sometimes unnecessary.
#ES DEDUPLICATOR OFFLINE#
UrBackup can be configured to accommodate a slow deduplicated backup storage.Īnother option is to use the Windows Server offline deduplication (and compression) available since Windows Server 2012 (with NTFS). If ZFS is chosen you should put enough RAM into the backup server otherwise deduplication will cause a huge slowdown. There are some other fuse file systems which support deduplication but those do not seem to be stable or performant. Btrfs does support offline deduplication.
#ES DEDUPLICATOR PROFESSIONAL#
There are also professional storage systems which do deduplication - sometimes in hardware. With deduplication data blocks which are the same in different files are saved only once on the hard disk. Usually it is 2TB though (with standard block size). With ext3 it can be as small as 16GB if the drive is formatted with a small block size. Then the maximum file size depends on the used file system. On Linux you have to enable the large file support in the kernel and for the specific file system. On Windows NTFS supports very large files. The file system has to be able to handle them. The client images are saved into one large file. All Linux/Unix file systems support hard links and symbolic links. NTFS is able to handle both (Symbolic links (junctions) are supported since Windows Vista). The backup file system has to be able to handle hard links and symbolic links. Or use UrBackup server on FreeBSD/FreeNAS with ZFS.
