rsync备份和删除指定文件

文件异地备份时,需要将本地文件合并到服务器上,且不能删除服务器上已有的文件

rsync -avzP    --delete -f '+ MT_*' -f '- *.*' -f 'P **/'  -f 'P *.*'    --password-file=/root/sbin/rsync.password  /var/ztmis/ rsync@192.168.1.15::data-files

参数解释
-a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
-v, --verbose               increase verbosity
-z, --compress              compress file data during the transfer
-P                          same as --partial --progress
--delete                delete extraneous files from dest dirs
-f, --filter=RULE           add a file-filtering RULE

FILTER RULES

exclude, - specifies an exclude pattern.
include, + specifies an include pattern.
merge, . specifies a merge-file to read for more rules.
dir-merge, : specifies a per-directory merge-file.
hide, H specifies a pattern for hiding files from the transfer.
show, S files that match the pattern are not hidden.
protect, P specifies a pattern for protecting files from deletion.
risk, R files that match the pattern are not protected.
clear, ! clears the current include/exclude list (takes no arg)


上面的表达式,只同步"MT_"开头的文件,也同步删除"MT_"开头的文件,不同步本服务器其它文件,也保留目标服务器的其它文件
