  • Patent number: 12265454
    Abstract: An embodiment identifies a fileset used by an executing application. An embodiment generates, at a first time, a first snapshot of the fileset, the first snapshot comprising a first state of the fileset at the first time and a first indicator corresponding to the first state of the fileset. An embodiment selects, at a recovery time later than the first time, from a sequence of snapshots of the fileset including the first snapshot, a recovery snapshot, the recovery snapshot comprising a recovery indicator, wherein the recovery indicator has a difference from the first indicator that is higher than a threshold value. An embodiment restores, using the recovery snapshot, the fileset to a state other than the first state, the restoring resulting in a restored application.

  • Patent number: 12086263
    Abstract: A computer-implemented method, according to one embodiment, includes: determining, for each pair of HCI systems where each pair includes a first HCI system coupled to another HCI system, a federation relationship setting that corresponds to each pair. The federation relationship settings are used to control a flow of data, as well as to control a flow of workload scheduling, between the first HCI system and the other HCI systems in the respective pairs. Moreover, determining a federation relationship setting that corresponds to a pair includes: determining whether a risk score which corresponds to the pair is outside a predetermined range. In response to determining that the risk score is outside the predetermined range, a restrictive federation relationship setting is assigned to the pair, and in response to determining that the risk score is not outside the predetermined range, a permissive federation relationship setting is assigned to the pair.
