How use Robocopy and incremental backup

[MarcusB]

Because of the lack of Ntbackup in Windows 2008 we would like use
robocopy to make backups. We was using robocopy before to backup
webservers folders but that we copied everything with /mir options.

We want make full backup one time per 4 weeks and than do incremental
every day. But we want to make incremental to another disk where
robocopy will copy only new files. How to do this?

From the robocopy Help file:
::
:: File Selection Options :
::
/A :: copy only files with the Archive attribute set.

Hi,

Actually, you will want to use the /M option:

::
:: File Selection Options :
::
/A :: copy only files with the Archive attribute set.
/M :: copy only files with the Archive attribute and reset
it.

With /A you keep recopuing the same files over and over; it would be more
like a differential backup.
With /M you copy only the files changed since your last incremental.

Oops - forgot about that one. Thanks for the correction.

Thank you, I missed this options.
How is with opened files in Robocopy? Is there the way to backup opened
files?

Take a look at the /MAXAGE option under "File Selection Options" and see
if you can't get that to do what you want.

Look at the /R and /W options.

Robocopy basically will Retry and Wait in between retries.

You can just wait, but AFAIK robocopy is not a VSS aware product and will
not copy locked files.
