Atitit. Improve backup file replication speed (3) ---- create a synchronization Delete script

 

 

1. Two Methods for creating a synchronous Delete script... 1

2. 1. info2 file from the recycle bin... 1

3. After the cleanup is completed, snap compares 1.

4. Npp replace gene del from lst 1

5. Code 2

 

1. Create two methods for synchronizing and deleting scripts ..

 

 

2. 1. The info2 file from the recycle bin...

Copy info2

{String s = "G: \ RECYCLER \ S-1-5-21-602162358-1284227242-682003330-500 \ info2 ";

Core. copy (s, "c: \ info2.txt ");

GeneDelBatShell> gene del. bat

 

3. After the cleanup is completed, the snap comparison

Trave2sqlUtil> snap. SQL

 

 

Compare select concat ('del ', '','" ', file,' "') as t FROM 'foldercount' where file not in (select file from foldercountclraftr)

Export lst.txt. bat

4. Npp replace gene del from lst

\ R \ n >>> "\ r \ n del"

 

 

5. Db ddl

Create table 'foldercount '(

'File' varchar (255) default null,

'SIZE' int (11) default null,

'Id' int (11) not null AUTO_INCREMENT,

'Extname' varchar (255) default null,

Primary key ('id '),

KEY 'I _ f' ('file ')

ENGINE = InnoDB AUTO_INCREMENT = 39702 default charset = utf8;

Which of the following is fast for file backup software and manual backup? Yes. How can I copy a 3 t hard drive data to another 3 t drive?

If you have empty data disks, just copy them on a computer. If the ghost can be as large as 3 t, the whole ghost should be the fastest to copy.

The actual speed at which USB 30 copies files

No legendary 5 GB per second ....

5400-to-mobile hard drive (3.0)
5400 to notebook (3.0)

Copied several hundred MB of resources from the hard disk, and the average speed is more than 20 MB per second...

I used this 3.0 hard drive to take the desktop (2.0 interface) Copy, the average speed of dozens of MB, up to 20 or 30 MB...

When buying a machine, I heard JavaScript say that two 3.0 machines can reach more than one hundred MB per second ..
