Through what method might rsync determine whether a file on the destination is from the source and since deleted, or created on the destination, when even you have no way of knowing. You would need a complete history of both filesystems, every create, rename, move, insert, delete, append, and unlink, in the correct order, in order to know which side a file came from, and in the case of duplicate filenames being created on each end, which one is the correct one. Actually, in that case, you'd also need to know the intentions of the users creating the files. This is not information that can be gathered by examining the state of the two filesystems, which is all rsync can do. Your application appears to call more for a shared filesystem scheme. Surely you're not mirroring or backing up to a location being locally changed in ways even you don't know. It can do only what you tell it to do.

Andy Lam <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 03/11/2002 10:43 AM To: [EMAIL PROTECTED] cc: (bcc: Tim Conway/LMT/SC/PHILIPS) Subject: Question on using rsync delete option Classification: Greeting. I'm so sorry that I launched the previous email by mistake and before I had a chance to complete it. Here is the summary of my previous question. We would like to use rsync to mirror the contents from our internal staging server ( A) to the external website (B) at our ISP without delete some existing files on B. On server B, we have applications that creates temporary lock files and customer upload files which I have no ideas what to exclude. The --exclude option would be my last resort, but I just want to know if there are better alternatives. If I use the --delete option in rsync, all the temporary files at the destination B will be deleted. In contrast, if I don't use the --delete option, the destination's temporary files will be intact, but any files removed from the source, A will not be deleted at the destionation B. It seems to me that the --delete option is either all or none with the --exclude option as exception. Maintainning a static list of exclude files would be very difficult and cumbersome for future maintainance. I have gone through the FAQ as far back as 2000, but couldn't find any similar question. Would appreciate very much if someone could please give me some pointers. Attached is the rsync command line that I use: rsync --verbose --update --progress --stats --compress --ignore-existing --delete --delete-after --recursive --times --perms --links --dry-run --rsh=/usr/local/bin/ssh --rsync-path /var/tmp/rsync /export/volx/documents/ destination_login@hostB:/export/volx (notice I left dry-run there for testing) Thank you in advance for your help .
