"LeonAutoBackup" V2.19 Copyright (C) 1998-2019 Leon Wang

This is a file backup utility runs in Windows 7/Vista/XP/2000/NT/ME/9x.

Feel happy to try this program and hope really helpful to prevent
your files from hard drive broken or virus invasion etc. Usually,
you can set network folder(s) in LAN as your "backup" folder(s),
because there's rather low probability that both drives got broken
in the same time. CD/DVD+RW drive is also an option.

It copies your files from "working" (source) folder(s) to "backup" (destination) folder(s) when the program start/exit or every specified time interval. There's an internal counter increasing every second while the program is running except the backup job is in progress.
If you has a schedule program running, LeonAutoBackup can be called from there with "/o" or "-o" command line switch. This tells LeonAutoBackup "run once" and exit immediately after all backup jobs done. In "run once" mode, either "When Start" or "When Exit" options are executed. To change options, just run LeonAutoBackup without switch.
You can specify exclusions with "?" and/or "*" wildcard and the days of deleted files you want to be kept in the backup folders.
To speed up backup job, you can select whether to check the file modification time by checkbox "Ignore file time". If it's disabled, the program will copy newer files only.

To work with multiple backup folders, "Chained" mode could be activated by checkbox "Chained". It works like below:
    Source -> destination 1
    Destination 1 -> destination 2
    Destination 2 -> destination 3
and normal mode works like this:
    Source -> destination 1
    Source -> destination 2

Another typical use of this program is to build a mirror folder, or many mirror folders to share files in your working (source) folder to other users who have no access right for your source folder. For instance, you have P: and N: mapped drives from LAN, and have write access to them, but your colleagues have only N: drive read-only, and no access to P: drive. You created P:\CAR folder and want to share it to others for read-only, then you can set P:\CAR as source and N:\CAR as backup folder, with shorter auto-backup time interval, and "Clear deleted/excluded files" checkbox enabled.

The setting of "Clear deleted/excluded files after () days" is also used by clearing
folder(s) after each backup session if enabled "Empty".

To install this program, just copy the file "LeonAutoBackup.exe" to any directory,
no setup or other library files needed.

To run, just execute "LeonAutoBackup.exe", suggest that create a
shortcut in Program\Startup group.

To uninstall, delete the "LeonAutoBackup.exe" and "LeonAutoBackup.ini", that's all.

Exclusion pattern examples:
 a) *             [all files in all subdirectories]
 b) *.tmp         [all tmp files in all subdirectories]
 c) c:\dir1\*     [all files in c:\dir1 and its subdirectories]
 d) c:\dir2\*.bak [all bak files in c:\dir2 and subdirectories]
 e) *\~*          [all files and dirs whose name begins with ~]
 f) *\folder settings\*  [so, it's just a simple string match]

  本软件适用于将自己的工作目录(源目录)中的文件备份到一个或多个有可写权限的共享目录(目的目录)中,  只要不是所有的计算机(硬盘)同时瘫痪, 可大大降低文件丢失或损坏的可能性。 另外, 本软件还可以用于在局域网上建立镜像目录。
  软件特点: 可设定备份间隔时间(分钟,注意该间隔时间的设置, 过长起不到备份保护作用,过短则不能利用其挽救误操作);无需备份的文件(可以使用?和*通配符); 旧文件在备份目录的保留天数; 可备份至多个"备份目录"; 可以同时设定多个工作目录及各自的备份选项。程序利用一个定时器在后台运行,每隔指定的时间间隔备份一次, 备份是通过将已存盘文件复制到指定目录而实现的,同时检查源文件的修改日期,    使之只对更新过的文件进行复制(此规则可由“忽略文件时间”选项取消)。为尽量防止文件损坏, 程序将不用0字节的源文件覆盖非0字节的同名备份文件, 也不允许备份目录与源目录(工作目录)路径完全相同。
