What is "full remote project"?

Comment 3 Vladimir Kvashin 2011-06-02 06:17:00 UTC

This is a project that reside on other file system, not masterfs.

Comment 4 Vladimir Kvashin 2011-06-02 06:21:55 UTC

I guess the reason is that in BackupFacility.java:209 we use FileUtil.toFile(file) and are copying files instead of just fileobjects.

Comment 6 Vladimir Kvashin 2011-06-02 06:25:54 UTC

I tried the fix attached, it works.
I'd like to push it if you don't mind.

Comment 7 Jan Becicka 2011-06-02 07:01:44 UTC

OK. Looks safe. Please push it.

Comment 8 Vladimir Kvashin 2011-06-02 08:30:32 UTC

I pushed it into releases701 as due to intensive work on 7.01 bugfixing cnd team is working in releases701 branch (and we need this change badly). It will be transplanted automatically into trunk (cnd-main trunk) today.
