# man rsync

rsync(1)

NAME
       rsync - a fast, versatile, remote (and local) file-copying tool

OPTIONS SUMMARY
        -e, --rsh=COMMAND           specify the remote shell to use
            --delete                delete extraneous files from dest dirs
        -n, --dry-run               perform a trial run with no changes made
        -r, --recursive             recurse into directories
        --stats

The '-a' is equals '-rlptgoD'. But General user cannot use 'goD' option. So General user must use -rlpt.


Local

rsync -avzh --stats /tmp/test1/ /tmp/test2.bk
rsync -avzh --stats /tmp/test1/ /tmp/test2.bk/

rsync -avzh --stats --delete /home/user1/ /tmp/user1.bk/


Remote

rsync -e ssh -avzh --stats --delete /home/user1/ user2@192.168.0.2:/home/backup/server1/home/user1/
rsync -e "ssh -i /home/user1/.ssh/nopass" -avzh --stats --delete /home/user1/ user1@192.168.0.2:/home/user1/backup/server1/home/user1/


Tips

Speed limit(--bwlimit)

rsync -e ssh -avzh --stats –-bwlimit=1250 FILE  user@192.168.0.2:/DIR/
--bwlimit=12500   # 100Mbps = 12500KBps = 12.5MB/s
--bwlimit=1250   # 10Mbps = 1250KBps = 1.25MB/s
--bwlimit=125    # 1Mbps = 125KBps
--bwlimit=62   # 500kbps = 62.5KBps


wildcard, include/exclude

rsync -avzh --stats --include='*.log' --exclude='*' srcdir/ dstdir/

rsync -avzh --stats --exclude='*.gz' srcdir/ dstdir/
rsync -avzh --stats --exclude='.*' srcdir/ dstdir/

rsync -avzh --stats --progress --partial  src:/path/to/log/2020-09\*.log  ./log
