where you think it's safe.At the end of the backup command you may see a hint: ' Tar:error exit delayed from previous errors ', in most cases you can ignore it.You can also use BZIP2 to compress files, BZIP2 is higher than gzip compression rate, but slower. If the compression ratio is important to you, then you should use BZIP2, "J" instead of "Z" in the command, and give the file a correct extension "bz2". The complete command is as follows:# tar CVPJF backup.tar.bz2–exclude=/proc–exclude=/los

ObjectiveAs a multi-user, multi-tasking operating system, the files under Linux are hard to recover once they are deleted. Although the delete command only deletes the file nodes, it does not really erase the contents of the file, but other users and some processes that have write actions will soon overwrite the data. However, for home use of Linux, or mistakenly

First, how to use the "RM-RF" command Under the Linux system, the command "RM-RF" can remove any data directly from the hard drive, without any hint, and Linux does not have the same function as Windows Recycle Bin, which means that the data cannot be recovered by conventional means after deletion. So use this command
