NTFS data streams. Broken by design on file copy?
for time have been having problems backups. vista , windows server 2008 made worse.
i use vss , robocopy backup filesystems backup location.
microsoft seems have broken functionality of robocopy design. ( http://support.microsoft.com/kb/912595 )
this kb tells us:
when try create, copy, or move file 2 logical units, cannot copy or move files using specific security settings on computer running version of microsoft windows operating system. problem seems occur files have alternate data streams linked them. additionally, may receive error message resembles following:
this means robocopy can not backup file has alternative data stream attached.
microsoft continues not bug, design. effectivelly ignoring problem , rendering robocopy tool broken too.
their workarounds no @ all:
- use staging server , automatic script. example, can use staging server has robocopy in notification mode.
- write windows explorer extension copy or paste specific set of permissions files. example, can use backup api instead of filecopy api.
group policies disabling adding of zone infromation don't work too.
does have suggestion or input on matter?
it seems want make backup of file system backup location on network. work around security limit in ntfs file system, please try use windows server backup feature on windows server 2008 backup file server network location? windows server backup uses vss technology take backups.
