摘要： A method, including receiving, by a secure processor housed in a disaster-proof casing located at a local site, recurring wireless signals from an application server and from a storage system that are collocated with the processor at the local site, the application server configured to store data to the primary storage system, and to mirror the data to a remote site, each of the wireless signals indicating a status of the application server or the storage system at a given time. A status log including the respective statuses of the application server and the storage system at the received times is stored to a memory in the casing, and subsequent to failures of the application server, the storage system and the mirroring, the status log analyzed to compute a data loss at the local site resulting from the failures of the application server, the storage system, and the mirroring.

摘要： A recovery unit for recovering data includes an antenna and a first wireless transceiver. The first wireless transceiver is configured to communicate via the antenna only with a second wireless transceiver of a storage unit that holds records associated with the data. When an event damaging at least some of the data occurs and the recovery unit is brought into proximity with the storage unit, the recovery unit receives the records from the storage unit for recovery of the data.

摘要： Methods, storage facilities and computer software products implement embodiments of the present invention that include mapping, by a storage system including one or more storage devices, a set of storage blocks on a given storage device to a redo log file configured to store transactions performed by a transaction processing system. An archiving condition is specified, and upon the transaction processing system completing a given transaction a copy of the given transaction is stored to the redo log file. Upon the archiving condition being met, the storage system can remap the set of storage blocks to an archive log file.

摘要： A method includes monitoring a sequence of transactions in one or more volumes. The transactions are transferred to a primary storage (112) in a given order, and are replicated to a secondary storage (114). The volumes belong to a volume group (204) for which the transactions are guaranteed to be replicated while retaining the given order. Artificial write transactions (228) are periodically issued to a protection application field, which is predefined in a given volume (212) belonging to the volume group. Records indicative of the transactions, including the artificial transactions, are stored in a disaster-proof storage unit (144). Upon verifying that a given artificial transaction has been successfully replicated in the secondary storage, the records corresponding to the given artificial write transaction and the transactions that precede it in the sequence are deleted from the disaster-proof storage unit.

摘要： Methods, apparatus and computer software products implement embodiments of the present invention that include storing a set of malware detection rules for a set of respective storage entities, each given rule indicating, when applied to a request to write to a given respective storage entity, whether the request originates from one or more malware applications that corrupt the storage entities. Upon receiving a new request to write data to a given storage entity, a given malware detection rule corresponding to the given storage entity is identified from the set of malware detection rules, and the identified malware detection rule is applied to the received new request so as to detect that the computer is infected with a given malware application. A responsive action can be initiated upon detecting the given malware application infection.
