The invention relates to a cluster type OTA upgrading method, which is applied between an OTA gateway and N terminals, each terminal communicates with the OTA gateway through a wireless channel, and the wireless channel is divided into an upgrading channel and a scheduling channel; dividing each working period of the OTA gateway into a competitive access period and a non-competitive access period;in the competitive access period, the OTA gateway works in a scheduling channel and broadcasts firmware information; in the non-competitive access period, the OTA gateway works in an upgrading channel to perform an upgrading packet issuing process; each terminal accesses the OTA gateway according to the firmware information broadcasted by the OTA gateway, and requests to allocate the communication time slot in the non-competitive access period; and the terminal requests to issue an upgrade package in the allocated communication time slot and executes an upgrade process. By adopting the upgrading method, the upgrading packet issuing efficiency is improved, the upgrading packet backup speed of all terminals is increased, the defects of small communication bandwidth and low speed of IOT equipment are overcome, meanwhile, the overall upgrading time of batch terminals is shortened, and the upgrading efficiency is improved.

The invention discloses a large file distributed backup method and device based on erasure correction technology, and the method comprises the steps that a backup proxy server gradually caches large file data into a memory according to the received large file backup request information of a client; the backup proxy service extracts the big file data pre-read into the memory according to the fixedblock size of each MB to obtain n source data blocks; the redundancy level of the erasure code is set as n + m, and m check data blocks are calculated based on the redundancy of the n source data blocks; metadata information disassembled into the data blocks is generated; the backup proxy service asynchronously and parallelly distributes the data blocks to n + m backup servers for distributed backup storage; and the backup proxy service monitors the backup data blocks of the backed-up large files. According to the method, the backup speed of the large file is increased, the check data block can provide secondary protection for the backup data with the minimum redundancy, and the reliability of the backup data is guaranteed while the backup storage space is saved.
