backup - How do you monitor DejaDup's progress? - Ask Ubuntu

i have "backup" dejadup app backing home folder encrypted external usb hard drive, takes hours. gui's "backup now" button grayed out, indicating it's running, , gnome says "starting scheduled backup". however, have no idea how long should take. there anyway progress info dejadup?

top shows duplicity process running option --log-fd=16. duplicity's manpage indicates file descriptor of log file writes status updates to. however, if run tail -f 16, error tail: no files remaining. how read log file descriptor?

i think can monitor this:

using ps, pid , log fd, e.g.

$ ps aux | grep duplicity username  12345 97.2  4.9 878235 345123 ?       rsl  02:21  15:02 python2 /usr/bin/duplicity --exclude=/run/media/..... --tempdir=/home/username/.cache/deja-dup/tmp --log-fd=18 

the pid 12345, , file descriptor 18.

then go /proc/pid/fd (/proc/12345/fd) , instead of trying tail file descriptor 18, use cat or grep.

$ cat 18 

this shows way info me. 90% of exclude globs.

$ grep "examining path" 18 

works seeing file being examined. if @ output, can focus on when finds files match (and don't need backing up) or when they're different.
