Grsync备份解决方案的建议设置是什么？

我设置了两个测试目录；一个在源上，一个在目标上，并测试了这些选项。这是我的结论：

No option selected: Files that are identical on the source and the destination are not copied. All other files are copied to the destination even if the destination files are newer. Extra files that are on the destination that do not exist on the source are left alone. This is a backup type operation. So if you never edit the files on the destination, this option (no option selected) will keep all your files up to date. Files that were copied to the destination in an earlier backup but later deleted from the source will remain on the backup copy.

Delete on destination: This is identical to the above option except the extra files that exist on the destination but not on the source will be deleted. If you accidentally delete a file or folder from the source but you have a copy on the destination, after this operation those files will be deleted from the destination. Use with caution.

Ignore existing: Do not copy files that are already exist on the source and destination drive, even if the file on the source is newer. The old files remain unchanged on the destination. As an example, if you modify some documents on the source drive and/or on the destination, they will not be copied.

Skip newer: Do not copy an old file on the source over a newer file on the destination. So if there is a destination file that is newer than the source file, the older source file will not be copied over top the newer destination file. But files that exist on the source but don’t exist on the destination will be copied. After this operation, the destination will contain all the newer files, whether the newer file existed on the source or on the destination.

Recommendations: I check Skip Newer and leave other options alone. This will make a backup where the destination contains the latest versions of the files. Older files will not overwrite newer files. Old files on the destination that have been deleted from the source will remain on the backup copy.

您可能要从备份中排除某些文件或文件夹。单击“高级选项”选项卡以执行此操作。这里有些例子：

--exclude = /。（不包括隐藏的点文件）

--exclude = * /图片

--exclude = * /音乐

--exclude = * /视频

--exclude = *。pdf（不包括pdf文件）
