Differential backup: Back up data based on full backup. Because the tar command cannot implement differential backup, this article explains how to use the dump and restore commands. Of course, the dump and restore commands can also implement full backup and Incremental backup. 1. Create Backup directory partition mounting [root@serv01 data]# mkdir /backup[root@serv01 data]# fdisk /dev/sdb[root@serv01 data]# fdisk /dev/sdc[root@serv01 data]# mkfs.ext4 /dev/sdb1[root@serv01 data]# mkfs.ext4 /dev/

RF interference can cause catastrophic problems with wireless local area network (WLAN) deployments. However, many companies are still able to make use of their wireless networks, and there is no trouble, but some companies after the installation of wireless network, but found that the network does not run as planned. Interference signals from external RF sources are often the culprit. Therefore, it is nece
