System and method for generating consistent backups using multi-snapshot analysis in virtualized computing environments

A non-transitory computer-readable medium storing a set of instructions for generating a backup of a file system, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the device to:
• capture a plurality of snapshots of the file system at predetermined time intervals and in sequence without freezing operation of the file system, wherein the file system supports a workload that is deployed in a cloud environment;
• verify each of the plurality of snapshots to determine whether the snapshot is valid or corrupted, wherein verifying each of the plurality of snapshots comprises mounting each snapshot, performing a file system check on each mounted snapshot, marking each snapshot as valid when the snapshot passes the file system check without detecting errors, and marking each snapshot as corrupted when the file system check detects any inconsistencies;
• select one of the snapshots marked as valid for backup of the file system in response to determining that at least one snapshot is marked as valid;
• initiate a repair process for snapshots determined to be corrupted in response to determining that no snapshot is valid;
• and
• designate the repaired snapshot as valid in response to successfully repairing at least one corrupted snapshot.

A system for generating a backup of a file system comprising:

• one or more processors configured to:
• capture a plurality of snapshots of the file system at predetermined time intervals and in sequence without freezing operation of the file system, wherein the file system supports a workload that is deployed in a cloud environment;
• verify each of the plurality of snapshots to determine whether the snapshot is valid or corrupted, wherein, to verify each of the plurality of snapshots, the one or more processors are configured to mount each snapshot, perform a file system check on each mounted snapshot, mark each snapshot as valid when the snapshot passes the file system check without detecting errors, and mark each snapshot as corrupted when the file system check detects any inconsistencies;
• select one of the snapshots marked as valid for backup of the file system in response to determining that at least one snapshot is marked as valid;
• initiate a repair process for snapshots determined to be corrupted in response to determining that no snapshot is valid;
• and
• designate the repaired snapshot as valid in response to successfully repairing at least one corrupted snapshot.
