The Data Domain Operating System (DD OS) is the intelligence behind Data Domain systems that makes them the industry’s most reliable and cloud-enabled protection storage. The second Dell EMC offering is Avamar: this unit de-duplicates data at the source via an agent on the host which offers savings on bandwidth utilization during backup.
The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. The scheme determines how and when each piece of ...
True continuous data protection is different from traditional backup in that it is not necessary to specify the point in time to recover from until ready to restore. [5] Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [5]
provisionally backing up data to a local staging backup device, possibly for later archival backup to a remote store device. Open file backup. the ability to back up a file while it is in use by another application. See File locking. Remote store. backing up data to an offsite permanent backup facility, either directly from the live data source ...
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.
Storage devices focused on holding computer data, e.g., HDDs, FDDs, and Iomega zip drives, use concentric tracks to store data. During a sequential read or write operation, after the drive accesses all the sectors in a track, it repositions the head(s) to the next track. This will cause a momentary delay in the flow of data between the device ...

This is a suitable method in the case of banking systems. [citation needed] In modern cloud architectures, or disk to disk backup scenarios, this is much simpler. Data is broken into chunks and placed on a cloud storage system. Metadata about the chunks is stored in a persistent system, which allows the system to assemble a point in time backup ...
