Abstract

The invention relates to a backup method based on sector data. The method includes: obtaining several backup time intervals, obtaining an average time interval as a backup period, calculating the deviation degree of each backup time interval, presetting the standard deviation degree, and comparing each backup time interval. There is a relationship between the deviation degree of each backup interval and the standard deviation, and count the number of the former less than the latter. If the number exceeds half, the average interval is taken as the backup period; Prepend the backup files that have been backed up many times to obtain the number of prepended files. When backing up in the next backup cycle, the corresponding number of files in the backup log list are backed up according to the log content, and then check whether the next file needs to be backed up. If no backup is required, the backup ends. The invention saves the computing resources required for backup and improves the efficiency of backup.

Description

technical field [0001] The invention relates to the field of data backup, in particular to a backup method based on sector data. Background technique [0002] With the popularization of computers and the advancement of information technology, especially the rapid development of computer networks, the importance of information security has become increasingly apparent. As long as data transmission, data storage, and data exchange occur, there will be data security issues, and data backup It is a means of data recovery when the security of data is lost. When the data in any host needs to be backed up, if the host uses a Linux system, then rsync, as a data mirroring backup tool under the Linux system, can back up the data of the host. rsync is the abbreviation of Remote Sync. This tool can not only synchronize remotely and support local replication, but also synchronize with other SSH and rsync hosts. It can retain symbolic links, hard links, file ownership, permissions, devic...
