Detailed Description
The following describes the technical solution of the present invention in detail with reference to the specific embodiments and the accompanying drawings, please refer to fig. 1.
Fig. 1 is a flowchart of a method of the present invention, and the present invention provides a data recovery method based on IRIG106 standard storage, which includes the following steps:
step 1: determining the position of damaged data and a data recovery condition;
step 2: searching data of which files are not completely damaged in the damaged data in a word unit according to the IRIG106 data storage standard and the data recovery condition;
and step 3: sorting all the recovered data, sequentially extracting the data into files, and then displaying all the recovered data by taking the files as units;
and 4, step 4: saving the specific file or all files to the computer-specified storage path.
The step 1 specifically comprises the following steps: damaged data files are generally stored on a solid state disk or directly stored on a hard disk of a computer in the form of files, if the data files are stored on the solid state disk, the disk needs to be connected to the computer through a SATA connection line, and in a device manager, a disk number is determined in a disk controller. If the data is stored in the hard disk of the computer, a file storage path needs to be determined, and no matter what form the data is loaded, the software is loaded in the form of a file stream; the damaged data is divided into directory block loss, directory block damage, file partial damage and file complete damage, wherein the completely damaged file cannot be recovered, and the rest damaged files can specify the recovery starting address and the recovery time period when being recovered. If the initial address is the searched initial offset address, the data is considered to cross the damaged severe area of the disk, and the data is directly recovered from the specified position; when the recovery time period is more for the files of the recovery data, the data is filtered by taking the time as a screening condition, and the efficiency of the data is improved.
The step 2 specifically comprises the following steps: starting from a data search starting address, searching data by taking a word as a basic unit, judging the type of the searched identification, wherein the identification type is divided into an invalid identification, a directory block identification, a file identification and a packet identification, the invalid identification is unidentifiable data, the directory block identification is directory block data, and the starting addresses and the file sizes of all files are stored; the file identification is file data, and a file initial address and a file degree are stored; the packet identifier is packet data, and stores packet start address, packet length, packet type (time packet, data packet, and other), and packet content, wherein one file is composed of a plurality of packets, and information of the plurality of files jointly constitutes a directory block. If no legal data identification is found at the end of the searched data, the data is considered to be completely damaged and cannot be recovered; if the directory block identification is searched, judging whether the directory block is complete according to the IRIG106 standard, if the directory block is complete, recording the block address of the directory, extracting all file information, finishing the search, if the directory block is not complete, considering that the directory block is damaged, and continuing to search the packet identification downwards; if the data packet identification is searched, firstly storing the initial address and judging whether the packet is a time packet or not, if the packet is the time packet, extracting the time information, then extracting the packet length according to the IRIG106 standard, searching the initial address of the next packet according to the packet length, judging whether the next packet has a file identifier or not, if not, judging whether the packet is a time packet or not, circulating until the next packet containing the file identification is searched, adding all packet lengths, calculating the file length and then storing, simultaneously, and taking the first time packet information in the file as the creation date of the file, taking the last time packet information as the file closing date of the file, finishing the recovery of the first file, taking the file identification packet address just searched as the starting address of the next file, and continuing the processes until all data is completely searched.
The step 3 specifically comprises the following steps: if the file is not searched in the step 2, skipping the step 4 and directly ending the data recovery process; if the complete directory block is searched in the step 2, extracting the initial address, the file size, the file creation date and the file closing date of all files in the directory block according to the definition of the directory block in the IRIG106 standard and storing the initial address, the file size, the file creation date and the file closing date in a database; and if the data packet identification is searched in the step 2, sequentially storing the initial address, the file size, the file creation date and the file closing date of each file into a database. After all the data are stored in the database, the data are screened according to the data recovery time period in the step 1, and then all the recovered data are displayed by taking a file as a unit.
The step 4 specifically comprises the following steps: and 3, selecting the data to be restored according to the displayed file in the step 3, and saving the file to the specified path at the rated speed by taking the packet as a basic unit, or saving all the data to the specified path at the rated speed.
