Linux backup Problems

Linux backup-general Linux technology-Linux technology and application information. For details, refer to the following section. There is a ghost backup tool in window. New linux users often ask if there is a tool similar to ghost in linux. Now I will talk about the linux backup methods I know:

1. ghost can also be used to back up linux. It does not seem to be available in earlier versions. It is not recommended because linux has better tools.

2. The ghost-like tool in linux has forgotten its name and is not recommended for the same reason.

3, tar, linux packaging tool, the most used tool, the parameters are as follows:

-J is packed in bz2 compression mode.
-Z is compressed in gzip mode.
-C: Only package files
-X unpack the file
-V: Output details
-F specifies the file name, which must be followed by the file name
-P: when the absolute path is used, remove/convert it to the relative path. Because it is packaged as an absolute path, when the package is unwrapped, it is also removed to the absolute path to overwrite its own file.
-P does not change the file attributes.
-Exclude excluded files

4. cp and replication tools are also very powerful. The parameters include apdrpslufi.

5. dd: complete backup partitions

-If source file-of target file, bs = block size count = fast quantity, conv specifies the conversion option.

6. cpio. I only know that this command is good and can be used with find. The specific usage is unclear.

I know so much about it.
