使用rsync备份和恢复文件脚本

tfengjun

Note:
To use the following scripts, you need to install:
   * tcl, expect, ssh, rsync on local machine
   * ssh, rsync on remote server
and ssh, rsync commands must in both sides' PATH environment.
Suggested versions:
tcl: 8.4.15
expect: 5.43.0
rsync: 3.0.2
How to install:
tcl:
     cd unix
     ./configure --prefix=/usr
     make && make install
     make install-private-headers
     ln -sv tclsh8.4 /usr/bin/tclsh
expect:
     ./configure --prefix=/usr --with-tcl=/usr/lib \
     --with-tclinclude=/usr/include --with-x=no
     make
     make SCRIPTS="" install
1. bak.sh is used for backing up contents under /mnt to remote server:
usage:
./bak.sh remoteip directory user password
e.g.
./bak.sh 192.168.22.110 /cas_bak root 123456
change SRC in the script if you want to backup other directory.
2. restore.sh is used for restoring files back:
usage:
./restore.sh remoteip directory user password
e.g.
./restore.sh 192.168.22.110 /cas_bak root 123456
change DEST in the script if you want to restore to other directory.
RETURN VALUE:
100: backup/restore success
101: No route to host
102: password incorrect
103: connection refused
104: incorrect command line arguments
