Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. [1] Unlike file copying, disk cloning also duplicates the filesystems, partitions, drive meta data and slack space on the drive. [2]
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
File-by-File Restore The ability for users to restore files themselves, without the assistance of a Service Provider by allowing the user select files by name and/or folder. Some services allow users to select files by searching for filenames and folder names, by dates, by file type, by backup set, and by tags. Online access to files
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 ...
Sending backups off-site also ensures that there is a copy of pertinent data that is not stored on-site. Although some organizations manage and store their own off-site backups, many choose to have their backups managed and stored by third parties who specialize in the commercial protection of off-site data.
^14 External hard drive support: Can refer to an alternate backup destination or whether the service can back up external drives. ^15 Hybrid Online Backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a D2D2C (Disk to Disk to Cloud) appliance encrypts and transmits ...
Backup software are computer programs used to perform a backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of data loss ; [ 1 ] hence, they are very useful to users.
