Described methods and systems for copying a source volume to a target volume that include a combination of concurrent copying and a copy-on-write (COW) technique that improves the reliability of the backup process and requires fewer resources during a given backup instance than the processes of the prior art.

Copy-on-write systems and methods

The disclosure provides methods and systems to perform data backups of protected data. According to an embodiment, a nominal backup schedule is received, and a time differential between the nominal backup schedule and a current time metric is determined. If the time differential is greater than a threshold, the backup schedule is modified so that times indicated in the modified backup schedule are at a higher frequency than a frequency of the indicated times of the nominal backup schedule. In another embodiment, if a reliability metric is greater than a corresponding threshold, the backup schedule is modified so that times indicated in the modified backup schedule are at a higher frequency than a frequency of the indicated times of the nominal backup schedule.

Adaptive data backup scheduling based on reliability metric or metrics

The disclosure provides methods and systems for adaptive data retention. According to an embodiment, data backups are acquired from a protected computing device, and stored on a backup computing device. A retention policy is applied to selectively prune the data backups stored on the backup computing device. At least one reliability metric is used to decide to continue pruning according to a nominal schedule or prune according to a less aggressive schedule.
