How to log the actual transfer size reported by btrbk?

[ceremcem]

Partly related to #280

I try to capture all logs in order to parse later to get statistics, like so:

btrbk -c conf.calculated --progress -v run | tee mylog.txt

However, the transfer size information is not present in the mylog.txt. How can I redirect the summary: 50.7 MiByte in 4.0sec - average of 12.6 MiB/s line into the log file?

In case you have not found the answer, mbuffer is what is creating the progress text and it writes it to stderr (fd 2)

launching the backup with the following command should do the trick :

btrbk -c conf.calculated --progress -v run 2>&1 | tee mylog.txt

[ceremcem]

Can you get the lines with 2>&1 | tee ...:

summary: 18.8 MiByte in  0.4sec - average of 51.9 MiB/s                                                                                                                                          

Because I'm using exact same command btrbk -c conf.calculated --progress -v run 2>&1 | tee mylog.txt and it doesn't log those summary lines.
