The present invention is first write data by kernel interface in temporary memory space, and then behaviour will be repeatedly written in property again
It is merged into write-once operation, for there is the service life of the disk of write-in number that will be greatly prolonged.
Specifically, in the step S1, interim storage of the distribution one for data to be temporarily written is empty in memory in advance
Between.
The purpose for creating temporary memory space is thus to be avoided that in order to which data are temporarily written and directly write data into disk,
To reduce the write-in number of disk.
In the step S2, when needing that data are written to disk, the data of disk are written by kernel interface
It is written to the temporary memory space.
When needing that data are written to disk, the interim storage of step S1 creation is first write data by kernel interface
Space.
In the step S3, when reaching scheduled condition, by the data write once in the temporary memory space
Enter disk.
The present invention is that data are first written to temporary memory space, can will be described then when reaching scheduled condition

Scheduled condition therein can be that user is customized, be also possible to system default.
Scheduled condition can be time conditions, be also possible to times condition, be also possible to size condition.
Specifically, at predetermined time intervals, by the data one-time write disk in the temporary memory space.
Above situation, that is, time conditions, that is to say, that the data in timing transfer temporary memory space, when one section
Between, by the data one-time write disk in temporary memory space.It can will thus need repeatedly to write in previous a period of time
The data for entering disk are written disk using disposable mode, the write-in number of disk can be greatly reduced in this way, i.e., by one section when
Interior multiple write operations are merged into write-once operation.
The predetermined time, can be by user's customized setting in advance, it can also be such as settable pre- by system default
Fix time is 1 day, 2 days etc..
It further, will be in the temporary memory space when the write-in number of temporary memory space reaches pre-determined number
Data one-time write disk.
Above situation, that is, times condition, that is to say, that the data in fixed transfer temporary memory space, it is predetermined whenever reaching
When number, by the data one-time write disk in temporary memory space.It will can thus need in the past that disk repeatedly is written
Data, disk is written using disposable mode, the write-in number of disk can be greatly reduced in this way, i.e., will be write every certain
After entering operation, multiple write operations are merged into write-once operation.
The pre-determined number, can be by user's customized setting in advance, can also be such as settable pre- by system default
Determining number is 100 times, 200 times etc..
Further, when the data in temporary memory space reach predetermined amount, by the data in the temporary memory space
One-time write disk.
Above situation, that is, size condition, that is to say, that the data in temporary memory space are quantitatively shifted, it is predetermined whenever reaching
When amount, by the data one-time write disk in temporary memory space.Thus it by previous can need that disk is repeatedly written
Data are written disk using disposable mode, the write-in number of disk can be greatly reduced in this way, i.e., will be whenever the data of write-in
When reaching predetermined amount, multiple write operations are merged into write-once operation.
The predetermined amount, can be by user's customized setting in advance, can also be such as settable predetermined by system default
Number is 200M, 500M etc..
Further, the temporary memory space is provided with multiple, and for different types of data to be temporarily written.
That is, more than one temporary memory space can be arranged in the present invention according to the actual situation, the temporary space can be set
It sets multiple.This multiple temporary memory space can be used to that different types of data are written.
Such as 3 temporary memory spaces of setting, one of temporary memory space are used to be written document data, one is interim
Memory space is used to be written image data, and a temporary memory space is used to that video data is written.
Certainly, it is not limited only to that temporary memory space is arranged using aforesaid way.Using the multiple temporary memory spaces of setting
Benefit be that can classify to be judged.Such as some temporary memory space, scheduled condition can be time conditions,
For another temporary memory space, scheduled condition can be times condition, and is directed to and remains next temporary memory space,
Its scheduled condition can be size condition.
Because the data of each type are for a user, operating habit is different, some data are although small, but write
It is higher to enter the frequency, although some data are big, the write-in frequency is smaller or some data infrequently operate etc..
So scheduled condition can be arranged as needed for each temporary memory space, then judge whether to reach predetermined
Condition, when reaching scheduled condition, then by the data one-time write disk of temporary memory space.
In addition, the total amount of all temporary memory spaces can be preset in the present invention, then temporarily deposited for each again
It storing up space and distributes a ratio, temporary memory space each in this way will determine itself size, and each temporary memory space
Size may be the same or different, such as some temporary memory space is larger, some temporary memory space is smaller.
Further, the ratio that the temporary memory space accounts for memory is no more than 10%.I.e. all temporary memory spaces it is total
Amount account for memory ratio be no more than 10%, such as in save as 2G, then the total amount of all temporary memory spaces be 200M, in this way may be used
Influence system is avoided to operate normally.

The corresponding system of group is called.
Linux system is abstracted into VFS (Virtual File in order to be compatible with several operation systems, various file system
System, Virtual File System), VFS can provide one group of unconsummated interface, and then different file system provides different realities
It is existing.
One piece of disk can divide multiple areas, the corresponding file system in each area.Divide again in EXT4 file system multiple
Have in group, each group:
Super block: the information such as total amount and usage amount of record inode and data block；
Inode: the position data block where storing the metamessage and file content of file；
Data block: storage file content, a file may use multiple data block.
Carrying out, disk write is fashionable, can create the file of an entitled data of file in current directory.Corresponding disk
It adds an inode (index node) to be used to record the data file, the file being then associated with the inode where it
In, it can thus be pressed from both sides by this document and find this document.Then data file, which corresponds to, will record a data in inode
block。
File system is specifically to call Block I/O interface write magnetic disk.In Linux, I/O layers of Block are provided, is used
In encapsulation to Block equipment operation.The equipment that Block equipment is to one fixed block data of random read-write, such as HDD are hard
Disk, a sector (Sector) of HDD hard disk are exactly its minimum read/write unit.The minimum read/write unit of general HDD disk is (also
It is sector) it is 512 bytes.That is, 10 bytes are written and 512 bytes of write-in are all corresponding primary on HDD disk
Block I/O。
File system can be called needing data to be written to be converted into Block I/O.Due to Block equipment write-once
When with addressing being specific consumption, it so Block I/O can't be written immediately, but can cache in the queue, carry out a wheel and merge
It is operated again later with resetting, achievees the purpose that optimize performance.
