Describedly utilize remaining space to carry out backup to the file meeting backup request to be specially: in other separate physical storage unit outside the physical memory cell at this file place, write the image file of this file, and the separate physical storage unit being written into file mirrors there are enough remaining spaces to hold this image file;
Step 380, shows the fileinfo of the hardware information in memory device, memory information and storage to user;
Described hardware information comprises: the failure message of memory device, other information of memory device;
Described memory information comprises: the capacity of total volume, the capacity writing non-duplicate data, permission write new data;
Described fileinfo comprises: the fileinfo that can read and the fileinfo lost;
3) method of deleted file, step is as follows:
Step 410, receives removal request, deletes the file in memory device, deletes the file mirrors that content comprises original and may exist;
Step 420, reads the hardware information of current storage devices, memory information and fileinfo;
Described hardware information comprises: the failure message of memory device, other information of memory device;
Described memory information comprises: the capacity of total volume, the capacity writing non-duplicate data, permission write new data;
Described fileinfo comprises: the fileinfo that can read and the fileinfo lost;
Step 430, judge whether to need to arrange to optimize storage space, judgment value is that "Yes" carry out step 440; Judgment value is that "No" carry out step 450;
Step 440, arranges and optimizes storage space;
Described arrangement is optimized storage space and is comprised: the concrete memory address in the physical memory cell enter to specify by file data storing and physical memory cell, file data is shifted between different internal physical storage unit, the image file data of backup are deleted;
Step 450, analyzes the file in current state memory device, and the need of performing new backup policy, judgment value is that "Yes" carry out step 460; Judgment value is that "No" carry out step 470;
Step 460, according to memory device residual capacity and file importance, automatic screening meets the file of backup request, utilizes remaining space to back up the file meeting backup request;
The file that described automatic screening meets backup request comprises: according to file attribute information, analyzes the backup important level obtaining this file, and under current storage status, the backup feasibility conclusion value of this file;
The file that described automatic screening meets backup request also comprises: by under current storage status, and file backup is that " feasible " and the relatively high file of backup important level are as the file meeting backup request;
Described file attribute comprises: the storage space information of the size information of file, the temporal information of file, file, the operation note information of file;
The backup feasibility conclusion value of described file is specially: under current storage status, this file backup is " feasible " or " infeasible ", and its basis for estimation is whether the storage unit outside the physical memory cell at this file place has enough remaining spaces to hold this file mirrors;
Describedly utilize remaining space to carry out backup to the file meeting backup request to be specially: in other separate physical storage unit outside the physical memory cell at this file place, write the image file of this file, and the separate physical storage unit being written into file mirrors there are enough remaining spaces to hold this image file;
Step 470, shows the fileinfo of the hardware information in memory device, memory information and storage to user;
Described hardware information comprises: the failure message of memory device, other information of memory device;
Described memory information comprises: the capacity of total volume, the capacity writing non-duplicate data, permission write new data;
Described fileinfo comprises: the fileinfo that can read and the fileinfo lost.
