   A backup strategy requires an information repository, "a secondary storage space for data" [7] that aggregates backups of data "sources".

Consider a scenario where an editor comes and creates a new article at the same time a backup is being performed, which is being ...

   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.
