|Archive bit usage
What is archive bit?
Archive bit is one of the file attributes supported
by file system. System will automatically set archive bit whenever
you change this file or when you create new file. So meaning of
this attribute can be considered as "file needs backup".
How can you use it?
When you set "Use archive bit" in advanced file filters with
Synchronize It, it will copy only files where this bit is set.
In addition, it will clear this bit whenever file is copied. As
result, you can easily arrange incremental backup scheme,
when each folder will only have backup of files modified since last
As an example, here is simple command line to automatically
create daily backup archives:
wndsync.exe c:\project d:\back%D%M.zip /A /AUTO
This command line will automatically create archives with date in
filenames, like back0901.zip for September 1. Each archive will
have files modified since last backup.
