Various operations, functionalities and systems are described herein for backing up one or more node to an offsite location, restoring the one or more node from the offsite location, restoring the one or more node to a point-in-time (PIT) from the offsite location, cloning the one or more node from the offsite location, and cloning the one or more node to a PIT from the offsite location. Example operating contexts include one or more cluster of nodes running a NoSQL (Not only Structured Query Language) distributed database and backup, restore and/or cloning on those one or more cluster of nodes. |

1. A backup method comprising:
receiving a request to create an offsite backup of a node; identifying, by the computing system, a first set of files referenced in a first local backup snapshot of the node; copying, by the computing system, from the node to an offsite location, each of the identified first set of files; creating, by the computing system, a first offsite backup snapshot located at the offsite location by adding references to each of the first set of files at the offsite location; identifying, by the computing system, a second set of files referenced in a second local backup snapshot of the node; copying, by the computing system, from the node to the offsite location, each of the identified second set of files without copying from the node to the offsite location any of the identified first set of files; and creating, by the computing system, a second offsite backup snapshot located at the offsite location by adding references to each of the second set of files at the offsite location. |
