Locked files are deleted on sync with S3 on Windows

Suspected Bug

What is the problem you are having with rclone?

Hello guys!
In Windows rclone has a serious issue when changes occur in locked files on a S3 drive (for instance Word documents opened directly from the drive). After "Save" the file is DELETED on S3 and later it disappears locally.

Steps:

  1. Mount a S3 drive
  2. Store a Word docx file on the drive
  3. Open the file, change something and save. Leave the file open for a minute
  4. Close Word
    Result: The file is deleted.

What is your rclone version (output from rclone version)

rclone v1.52.3

  • os/arch: windows/amd64
  • go version: go1.14.7

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Windows 10, 64 bit

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

Amazon S3

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

rclone.exe mount blabla:blabla/ Y: --vfs-cache-mode writes -v

Also tried the other VFS cache modes with no success (except maybe for the "off" mode which invalidates the scenario).

The rclone config contents with secrets removed.

[blabla]
type = s3
provider = AWS
env_auth = false
access_key_id = secret1
secret_access_key = secret2
region = eu-west-1
location_constraint = eu-west-1
storage_class = STANDARD

A log from the command with the -vv flag

hello and welcome to the forum,

not sure we can call this a bug yet.

  • you would need to post a debug log
  • good idea to update rclone.
