Using cp, or a backup tool like mondo, tar, or some other? If using cp then the effective way to get all the data copied (and permissions to stay the same when copying from/to linux partitions) is to use "cp -a <file/directory>". That will maintain permissions and do the copy recursive. However, copying to a fat32 system with cp then trying to restore and expecting the permissions to be the same is (almost) a lost cause since fat32 has no concept of the linux ownership/permissions on files. IMHO, using tar to create an archive copy is the best and surest way to have a reliable copy when storing data on a different filesystem type. Missing data is often the result of not using proper options when issuing the command. > -- > Lloyd Hayes > > Personal Website > http://talkingstaff.bravehost.com/index.html > > Web Journal > http://lloyd_hayes.bravejournal.com/ >
