Data backup method and terminal

Embodiments of the invention disclose a data backup method and a terminal, relate to the technical field of communication, and aim to solve the problem that various data stored in the terminal cannotbe effectively backed up in the prior art. The method comprises the steps of obtaining a current running parameter of the terminal; according to the current running parameter, determining a target backup policy in at least one backup policies, wherein each backup policy comprises an index of to-be-backed-up data and a triggering condition needed to be met by backing up the to-be-backed-up data, and the target backup policy is a backup policy in the at least one backup policy when the current running parameter meets the triggering condition; and backing up the to-be-backed-up data indicated bythe index of the to-be-backed-up data in the target backup policy. 本发明实施例公开种数据备份方法及终端，涉及通信技术领域，用以解决现有技术中不能及时有效地备份终端中存储的各种数据问题。该方法包括：获取终端的当前运行参数；根据该当前运行参数，从至少个备份策略中确定目标备份策略；其中，每个备份策略包括待备份数据的索引以及备份该待备份数据需要满足的触发条件，该目标备份策略为至少个备份策略
