For as quickly as this goes away on my work laptop backup job (since not a whole lot is added each time), mine appears after a quick glance to be running right. But Iāll pay attention to it more closely in the coming days to make sure Iām right.
Thanks. Honestly Iāve only been noticing that it happens when setting up test jobs so theyāre mostly initial runs thus take longer. (And maybe thatās why Iām seeing it in the first place.)
Iāve seen this same issue when manually running jobs, I have 2.0.3.9. Although really I never paid any attention to that since it has never really been correct anyways since my first testing with 2.0.3.2 until the latest 2.0.3.9.
Similar in my case!
No green progress bar on top, but if finishing the backup and verifying the files the green progress bar goes to 90% and finally 100%, no progress in between.
The ā2 filesā from your screenshot are 4 in my case, constantly, no matter how may files to backup. Maybe something with the parallel threads / processes which take care of the files to backup and encrypt?
I have set the parameter --paralell-somithing-I-do-not-remeber to 4 if I remember correctly. Havenāt checked yet what happens if I change the parallel threads to any other number than 4. Will do it next weekend.
Looked at the source code now for several days but have not figured out how to fix this.
This happens to me even if I purposefully hobble --concurrency-block-hashers=1 (default), --concurrency-compressors=1 (default 1), and --concurrency-max-threads=1 (default 0).
I havenāt tried checking yet but I wonder how far back youād have to revert to get the bar working againā¦that might help in identifying what part of the code needs to be fixed now.
I have become a pro in the meantime by changing back and forth the different commits
The green progress bar worked until commit v.2.0.3.5-2.0.3.5_canary_2018-04-13 (version bump) three month ago! A lot of great parallel processing came into play.
Then Kenneth fixed it partially with commit v2.0.3.7-2.0.3.7_canary_2018-06-17 because I reported a strange behavior with the lastPgEvent but the main bar stays a little weardā¦
Even rolling forward each commit did not get me closer to any solutionā¦ may it help someone else hopefully
There are a couple known reasons for this. One is due to a bug where a file can be momentarily counted twice against the ātotal bytes to processā number. This can send the ābytes remainingā number negative. Mostly noticeable on small backup sets where one file is a very large percentage of the total. This particular bug has been fixed in the Canary channel but hasnāt made it into the Beta releases yet.
The other known instance of it going negative is when files grow during backup. At the start of a backup job, files are enumerated and Duplicati gets an idea of ātotal bytes to process.ā If a file has grown by the time Duplicati gets around to backing it up, it can throw the ābytes remainingā into negative territory. Filesystem snapshots are one way to work around this problem.
If you saw it go negative and stay negative when there were still 960 files to go, Iām guessing it might be the second scenario in your case. Can you confirm that you are not using snapshots? Are you running on Windows?
