Does the copy command use cache?

Does the copy command use cache? Where is it located?
When uploading, there is no rclone folder in the default location and nothing was being written in the location specified by --cache-dir. Is a cache in the harddisk being used or not? I dont want unnecessary writes in the ssd when uploading using copy.

hello and welcome to the forum,

the rclone copy command does not use a cache.

Thanks for the answer. So does it mean it uploads chunks directly from the harddisk and it is possible to resume the upload after a broken connection within the retry limit and time period?

correct, no additional local disk space is used, no "unnecessary writes"

if there is a issue with file copy operation then rclone will retry within its limits, tho those limits can be tweaked.
using a debug log would show that.

ERROR : Attempt 1/3 failed with 1 errors and: corrupted on transfer: md5 crypted hash differ "1a270352a04596befb6661dbc452024c" vs "9903ac2b88e6a6396f77d920eeb73ab2"
ERROR : Attempt 2/3 succeeded

DEBUG : pacer: low level retry 1/10 (error Put ""

if you network went down and came backup within those limits then rclone would continue the upload or retry upload.
