Analysis of Remote Storage of Windows2000 secret weapon

Introduction of the function and characteristics of tools

The purpose of remote file storage has been briefly mentioned in the previous article. The diagnostic tools associated with it are also introduced. The tool described here is also a tool for remote storage of file services, which is known as the remote file Storage Analysis Utility (sqlremote Storage file analyze Utility). The program name is: Rsdir.exe. This is a command-line based tool that displays information in the current directory or its subdirectories of Remote Storage files. So what's the difference between the two tools with similar names? The main differences are: 1. Remote Storage of File diagnostic tools (diagnostic tools for short), focusing on the diagnosis and description of stored jobs during storage, such as the description of the database table structure, the exact meaning of each field, and so on. The Remote Storage File Analysis tool (the analysis tool for short), mainly analyzes the current directory or its subdirectories of the file information, and only the Remote storage volume within the manageable scope of the file location information. It can be seen that the two are very different in their use. Of course, you can also use Remote Storage of file databases to diagnose file system problems. Also has the simple execution function.

Second, the use of methods:

This tool can be opened in the command console. The complete syntax used is as follows: Rsdir [file_or_directory] [/s] [/f]. It is not difficult to see that the tool uses a very small number of parameters. Its parameter meanings are explained as follows:

File_or_directory the specified file or directory, displays the status of the file, and if you specify a file, displays whether it is a file that is moved to the remote.

/s Displays the file information in the current or specified directory and its subdirectories.

/F Displays the extended information for the file.

Interpretation of the meaning of the output information:

The information that is exported using the Profiling Tools is primarily the state of the file, which consists of a number of attributes, each containing one or more descriptive data that has numbers, strings, or logical values. Each has its own meaning. The following table describes the meaning of these attributes and descriptive data as follows:

Property name	Function and Value
Name	File name
Status	File status, which can be one of the following: Trunc: This is a file that has been censored. PREMIGR: This is a moving file. Mount: This is a file that can be assembled Normal: This file is a generic file that cannot be managed by a remote Storage system.
Attributes	Properties of File: A: Archival files C: Compressed Files E: Encrypted files D: Table of Contents H: Hidden files O: Off-line Offline Files R: Read-only files S: System files X:has Extended Properties Z: Sparse files.
Logical Size	The logical size of the file
Physical Size	File occupies the size of the physical space
Access time	Access time
Modify time	Modified Time
Fileid	ID identification number of the file
HSM Id	Unique identification of the data owner in the HSM
BAG Id	ID Identification of Bag
File Start	The offset of the start of the file relative to the Remote Storage "segment"
File Size	Size of File
Data Start
Data Size	The size of the file data in this segment of data
File Version ID	ID number of file version
Verification Id	ID number of the checksum
Verification Data	Checksum data used in remote Storage
Recall Count	Count
Data Stream Start	Data Flow start position
Data Stream Size	The size of the transmitted data stream
Data Stream	Simple description of Data flow
Data Stream CRC Type	Type of data flow checksum
Data Stream CRC	Description of the location and size of the data to be validated
Migration time	Time of data Movement (transfer)
Last Recall time	Time of last access to data

Iv. examples

If run: Rsdir \test, you can get two files: Test71.tst and TEST72.TST, as for the details of these two files are not in our discussion. Please refer to the relevant information. But roughly speaking, this file is used in conjunction with the/F switch in the command.

For example: The following is an example of this:

rsdir/f TEST59.TST

A file called Test59.tst is used. The output for this line of command is very long. But they all correspond to the fields in the table above.
