Thanks! I edited your post to make the command stand out a bit more and bold / italicize the difference.
I did some tests with a local destination backup (see below) but the end result is something’s going on (even with a local destination), but I couldn’t reliably replicate it.
If possible, can you do a test of --upload-throttle=1MB
and see if it works for you?
I tried running a local backup with –throttle-upload=25KB
and got a “Warning while running task xxxx” window with “Got 0 warning(s)” in it.
I then got 5 retries each on the following - both with Hash mismatch on file ...
errors:
Get with file duplicati-20180308T213015Z.dlist.zip
Get with file duplicati-i6735436af81a45b5bbd68ef999a63514.dindex.zip
Eventually the log summary showed:
Errors: [ Failed to process file duplicati-20180308T213015Z.dlist.zip => Hash mismatch on file “C:\Users\Me\AppData\Local\Temp\dup-27b3c118-2f9b-4c7c-8909-167304175f1e”, recorded hash: DY0vKz/ezWIYCcQgMyptJiTv0+pGm3DSI8fkkfwwF9g=, actual hash F+sho+hzvVuCcTUlN5ysiPvrNbvCOXG1bv6MXJVpeR4=, Failed to process file duplicati-i6735436af81a45b5bbd68ef999a63514.dindex.zip => Hash mismatch on file “C:\Users\Me\AppData\Local\Temp\dup-ca215f22-fc0f-43ed-a11b-24f1ffff7330”, recorded hash: td/lx+agGcBffag2DR2REyqQJLfGTHb3NvbuEIxqiWI=, actual hash wQzF4oSFE0MmDQh7Wuapv2Z1ckzsMfjslDap8D15qB4= ]
Here are some more results:
--throttle-upload=25000
→ ERRORS (aka ~25KB but in bytes)--throttle-upload=50KB
→ ERRORS--throttle-upload=1024KB
→ ERRORS 50% of the time (aka 1MB but in KB)--throttle-upload=2048KB
→ no errors (aka 2MB but in KB)--throttle-upload=5120KB
→ no errors (aka 5MB but in KB)--throttle-upload=10240KB
→ no errors (aka 10MB by in KB)--throttle-upload=1048576KB
→ no errors (aka 1GB but in KB)--throttle-upload=1MB
→ no errors--throttle-upload=25GB
→ no errors--throttle-upload=25TB
→ no errors
Note that in all cases with errors they came during the “Verifying …” step - so your backups are working just fine, it’s the verification step that’s failing.
