DFS-R intermittently fails to replicate some files

greetings,

i've setup new dfs replication group has replicated 30 gb of data, totalling on 100k file.  new files , folders replicated , works great.  i've noticed 2 issues.

first, have ~8 files not being replicated.  example, one 250kb pdf file exists on server1 (sbs2008) not server2 (2008 r2).  there 8 such files can robocopy other server, concerns none less.  removed file filters replicated folders properties also, isn't being caused file or subfolder filter.

secondly, i've found file has newer modified date: 3-14-2011 on server1 vs. 3-13-2011 on server2.  checksums match, file contents identical, file modified dates still differ shows inconsistency.

i believe servers have updates applied, , believe i've applied dfs relevant hotfixes.

thanks in advance,

patrickfromsc

hi patrickfromsc,

please check file property of these problematic pdf files. according experience, dfs-r won't replicate temprary file. may check file property following fsutil command.

fsutil usn readdata myfile.pdf

by design, dfsr not replicate files if have temporary attribute set on them, , cannot configured so.
 
reason dfsr not replicate files temporary attribute set considered short-lived files never want replicate. using temporary attribute on file keeps file in memory , saves on disk i/o. therefore applications can use on short-lived files improve performance.
