I think if you use the --dry-run option in rsync it may tell you how much data would have been transferred. -Rob The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

[BackupPC-users] how to examine progress of backup
I use rsyncd to backup both, windows as well as linux clients. Is it possible to examine or calculate the progress of an actual running backup? One Idea would be to calculate the duration of the last backups and assume the actual backup will have the same performance. But this can be wrong if some new (big) files had been added. Another Idea is to examine the filespace of the share and calculate the estimated duration based on the last transfer rates. But this can be wrong if some (big) files are in the exclusion list. Any Ideas? br and have a great new year!

Any Ideas? I don't think it is even possible to guess how much rsync will transfer on a changed file without running through the whole comparison. rsync does have --progress which I find very useful, this at least displays how many files need to be looked at, and how many are left to examine. It is a better indication than nothing, but not exactly a good time estimate... especially if the last files are very large and/or with a large amount of changed data/new etc. Personally, I would like it if this data could be collected by backuppc and displayed in the log at least. ie, at the beginning of the log it could store how many files should get looked at, and when it fails part way, it can display how many files it has done, and how many are left Also this could be shown on the status page... In fact, the status page could even show some additional interpreted data such as Building file list, and File transfer in progress or better File 1234 of 2344 in progress, a bw rate over the past 60 secs would also be nice (to know it hasn't stalled when it shows the same file number for a long period of time). Of course, if you do this for rsync, then everyone will want the same features for tar/smb/ftp/etc...

But I find no output of it. Because I run rsync in a daemon mode? br Matthias -- Don't Panic -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
