Hey all, Any suggestions on how to estimate how much data rsync would synchronize on average in a given installation? Assume that a full rsync has already run and the only data being updated is just the daily diffs.

To do that, you?d have to find out how much data is being added daily. I would think that would closely resemble your nightly diff copies. _____________________________ Stephen Zemlicka Integrated Computer Technologies PH. 608-558-5926 E-Mail <mailto:stevezemlicka@gmail.com> stevezemlicka@gmail.com _____ From: rsync-bounces+stevezemlicka=gmail.com@lists.samba.org [mailto:rsync-bounces+stevezemlicka=gmail.com@lists.samba.org] On Behalf Of Noam Birnbaum Sent: Tuesday, October 02, 2007 3:22 PM To: rsync@lists.samba.org Subject: estimating nightly diffs Hey all, Any suggestions on how to estimate how much data rsync would synchronize on average in a given installation?

* Any suggestions on how to estimate how much data rsync would synchronize on average in a given installation? Try recording the stats at the end for a few days and see what the results are. If you really want to get a better idea import the data into a spreadsheet / keep a running average..

Pass --stats to rsync to get a bunch of useful information about how much it is transferring. If you don't yet trust rsync to write to the real destination, you can use a dummy destination and --compare-dest to the real one; this will give you the same statistics. Matt
