Azureblob exceeding 100% per file / amount transferred is double the amount of files

Suspected Bug
1

What is the problem you are having with rclone?

Similar to Percentages Exceeding 100% all my files exceed the 100% progress per file up to 200%. Furthermore, it uses double the amount transferred, so for 3 TiB of files it uses 6 TiB of traffic. This happens on azureblob with the default block size of 4MiB and files of about 64MiB. This stops happening if I set chunk size to 128Mi. Also, setting chunk size to 128Mi (larger than any file in repo) significantly reduces transactions. Is this because of fewer (no) multi-part / multi-chunk uploads?

Run the command 'rclone version' and share the full output of the command.

rclone v1.69.1

  • os/version: nixos 25.05 (64 bit)
  • os/kernel: 6.12.35 (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.24.4
  • go/linking: dynamic
  • go/tags: cmount

Which cloud storage system are you using? (eg Google Drive)

azureblob

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone sync $snapshot_path $target_dir --config $rclone_config --delete-after --stats-log-level NOTICE --fast-list --azureblob-access-tier archive

for which I added

--azureblob-chunk-size 128Mi

later on.

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

A log from the command that you were trying to run with the -vv flag

I already restarted with the chunk size setting. If absolutely necessary I'd have to rerun, sorry.

There were some changes recently regarding traffic accounting I think.

Could you try with the latest rclone? v1.70.3?

No point to investigate some old rclone version....

Here is the -vv log with rclone v170.3.

I did some try'n'error and the transferred amount seems to double only on using crypt remote. With normal remote everything is fine.
