Synchronizing storage devices outside of disabled write windows is described. A system receives, via a backup/restore application interface, a list of identifiers corresponding to source storage devices to be backed up. The system enables a target storage device to synchronize with a source storage device. The system sends, via the backup/restore application interface, a request to disable any write commands to the source storage devices corresponding to the list of identifiers. The system creates a snapshot of the source storage device. The system sends, via the backup/restore application interface, a request to enable any write commands to the source storage devices corresponding to the list of identifiers.
