2. Nearline storage - Wikipedia

   en.wikipedia.org/wiki/Nearline_storage

   Nearline storage (a portmanteau of "near" and "online storage") is a term used [1] in computer science to describe an intermediate type of data storage that represents a compromise between online storage (supporting frequent, very rapid access to data) and offline storage/archiving (used for backups or long-term storage, with infrequent access to data).

Near store. provisionally backing up data to a local staging backup device, possibly for later archival backup to a remote store device.

   Time Machine is the backup mechanism of macOS, the desktop operating system developed by Apple.The software is designed to work with both local storage devices and network-attached disks, and is commonly used with external disk drives connected using either USB or Thunderbolt.

5. Continuous data protection - Wikipedia

   en.wikipedia.org/wiki/Continuous_data_protection

   In some situations, continuous data protection requires less space on backup media (usually disk) than traditional backup. Most continuous data protection solutions save byte or block-level differences rather than file-level differences. This means that if one byte of a 100 GB file is modified, only the changed byte or block is backed up.

6. Virtual tape library - Wikipedia

   en.wikipedia.org/wiki/Virtual_tape_library

   A VTL presents a storage component (usually hard disk storage) as tape libraries or tape drives for use with existing backup software. Virtualizing the disk storage as tape allows integration of VTLs with existing backup software and existing backup and recovery processes and policies. The benefits of such virtualization include storage ...

7. Disk-based backup - Wikipedia

   en.wikipedia.org/wiki/Disk-based_backup

   Disk-based backup refers to technology that allows one to back up large amounts of data to a disk storage unit. It is often supplemented by tape drives for data archival or replication to another facility for disaster recovery. Backup-to-disk is a popular in enterprise use for both technical and business reasons.

   The most desirable RPO would be the point just prior to the data loss event. Making a more recent recovery point achievable requires increasing the frequency of synchronization between the source data and the backup repository. [65] Recovery time objective (RTO): The amount of time elapsed between disaster and restoration of business functions ...

9. Disk cloning - Wikipedia

   en.wikipedia.org/wiki/Disk_cloning

   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]
