Why junction points and no ACLs?

Feb 16, 2012 at 8:01 PM

I stumbled upon this project while searching for a way to generate a file list for 7zip incremental backups.  I'm glad to see I don't have to reinvent the wheel!

Forgive me for asking a few simple questions as I could not discover the answers for myself in the documentation or forum.

1. For what purpose are junction points used in 7zbackup?

2. Home page says ACLs are not saved.  Why not?  7zip saves file and folder ACLs natively, does it not?

Best regards.

Hello baodad,

I am glad to answer your questions.

1. Junction points are used to create a "virtual root" where to link different sources to a single point-of-entry. This is necessary as 7zip still has an odd behaviour : scanning different sources which are not child of the same root, causes an uncomfortable (and IMHO unreal) "duplicate file name" error.

2. As far as I know 7zip can *not* save ACL. It can Store NTFS timestamps for files: Modification time, Creation time, Last access time. Nothing else.
