Abstract
The invention provides a file permission back-up method applied in a new technology file system (NTFS). The system includes a centralized data acquisition module (1), a catalog data organization module (2), and a file access back-up recovery module (3). The centralized back-up data acquisition method is used for obtaining file permission and attribute information in the file system; file information data are organized into a catalog file and backed up to a medium server so as to prevent that domain user rights are lost because of system crash or abnormality; the file cannot be read or manual reconfiguration of the user rights is troublesome.
Description
Technical field
The present invention relates to the Computer Applied Technology field, specifically a kind of file permission backup method that is applied under new technology file system.
Background technology
Just as telephone directory provides the individual the same with mechanism phone information service, ActiveDirectory provides a kind of like this directory service, and it can be stored and access all networked resources (as computing machine, printer, user, Shared Folders, message queue etc.) for information about easily.ActiveDirectory plays a part switchboard in network environment.It helps user and application program to search and access the resource of these networkings, and they are connected with each other.What is more important, it can guarantee that user or the application program of only obtaining the authorization could access these resources safely.Can be for each catalogue, file arrange corresponding file access authority under new technology file system, comprise AD territory authority, can manage resource more easily like this.And when operating system is collapsed or occur extremely needing refitting, be that the file access authority of file and catalogue configuration all can be lost, file resource will occur like this to access unsuccessfully, need to manually carry out configuration again. beforeEspecially in the time of the file permission very complex, carry out to waste a large amount of time from new configuration.Unresolved the problems referred to above, the present invention is separately for information such as file access authorities, and Adoption Network communication and the mode that the io operation separates utilize catalog storage file information data, and more reliable file permission backup and reset mode are provided.
Summary of the invention
The purpose of this invention is to provide a kind of file permission backup method that is applied under new technology file system.
The objective of the invention is to realize in the following manner; use centralized backup set data capture method to obtain file permission and attribute information under file system; file information data is organized into the catalog file backup to media server; in case locking system collapses or extremely causes the loss of territory user right; and file can't read or need to manually reconfigure territory user right trouble; system comprises: centralized data acquisition module (1), catalog Organization of Data module (2), the backup of file access authority recover module (3), wherein
Centralized data acquisition module (1) is used for concentrating the path list information of obtaining backup file, scan by recursive algorithm the backup source path that the user sets, compare file or the catalogue that determines whether as the needs backup by the path, form a backup file path list information, recover module (3) routing information to offer the backup of file access authority, be used for the backup operation of fileinfo;
Catalog Organization of Data module (2) is used for the information of each file of storage, and the catalog structure is as follows:
typedef struct _CATALOG_INFO {
DWORD dwSize;
DWORD dwFileType;
DWORD dwFileSizeHigh;
DWORD dwFileSizeLow;
DWORD dwFileAttribute;
FILETIME ftCreatedTime;
FILETIME ftLastAccessTime;
FILETIME ftLastWriteTime;
int nBackupSet;
DWORD dwFilePathLen;
DWORD dwFileDACLLen;
#define FilePath(ptr) ((char *)ptr + sizeof(struct _CATALOG_INFO))
#define FileDACL(ptr) ((char *)ptr + sizeof(struct _CATALOG_INFO) + ptr->dwFilePathLen)
}CATALOG_INFO, *PCATALOG_INFO;
member in structure represents respectively: the catalog file size, file type, the high byte of file size, the low byte of file size, file attribute information, the document creation time, the last access time of file, the last write time of file, backup set ID, file path length, the file permission message length, file path information, file permission information, each file can be stored as catalog information with above-mentioned relevant information, the catalog information of each file is written in the catalog file goes, write and whole catalog file is sent to media server after completing and preserve,
The backup of file access authority recovers the access rights that module (3) is used for the back up or restore file, the backup file path list information that provides according to centralized data acquisition module (1) offers to the corresponding file access control table of each path extraction information the tissue that catalog Organization of Data module (2) is carried out catalog information.
In whole backup procedure, Backup Data is buffered in client, but backup just can generate complete backup set after completing, and just can begin the transmission of data, to improve the transfer efficiency of network.
Described file permission information is ACL file access control table, is used for the log file access authority information.
Described catalog file is the relevant information of having stored one group of file, and this information comprises: catalog file size, file type, file access time, file attribute, backup set ID, file absolute path and file permission information.
File access authority restore funcitons is by original route information, extracts corresponding file information data and return in original from catalog, completes the rejuvenation of file access authority.
The invention has the beneficial effects as follows: use centralized backup set data capture method to obtain file permission and attribute information under file system; file information data is organized into the catalog file backup to media server; in case locking system collapses or extremely cause the loss of territory user right, and file can't read or need to manually reconfigure territory user right trouble.
