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...
