Well, this is probably my final test with the Evernote folder, and some results were strange, and i really need your help to understand what happened at the end…

Some notes:

Upload and time values were obtained from the log of each software.

```
Duplicati:
bytes uploaded = “SizeOfAddedFiles”
upload time = “Duration”

```

```
Duplicacy:
bytes uploaded = “bytes uploaded” in log line “All chunks”
upload time = “Total running time”

```

Rclone was used to obtain the total size of each remote backend.

In the first three days I used Evernote normally (adding a few notes a day, a few kb), the result was as expected:

**BUT, this is the first point I didn’t understand:**

**1) How does the total size of Duplicacy backend grows faster if daily uploading is smaller (graph 1 x graph 2)?**

Then on 26th I decided to organize my tags in Evernote (something I already wanted to do). So I standardized the nomenclature, deleted obsolete tags, rearranged, etc. That is, I didn’ t add anything (bytes), but probably all the notes were affected.

And the effect of this was:

That is, something similar to the first few days, just greater.

Then, on day 27, I ran an internal Evernote command to “optimize” the database (rebuild the search indexes, etc.) and the result (disastrous in terms of backup) was:

**(and at the end there are the other points for which I would like your help to understand)**

**2) How could Duplicati upload have been so small (57844) if it took almost 3 hours?**

**3) Should I also consider the “SizeOfModifiedFiles” Duplicati log variable?**

**4) If the last Duplicati upload was so small, why the total size of the remote has grown so much?**

**5) Why did Duplicacy last upload take so long? Was it Dropbox’s fault?**

I would like to understand all these doubts because this was a test to evaluate the backup of large files with minor daily modifications, and the real objective is to identify the best way to backup a set of 20Gb folders with mbox files, some with several Gb , others with only a few kb.

I look forward to hearing from you all (especially @kenkendk).
