Starting from July 2023 SHA1 support is being phased out in OnedrivePersonal in favour of QuickXorHash. If necessary the--onedrive-hash-type flag (or hash_type config option) can be usedto select SHA1 during the transition period if this is importantyour workflow.
Before rclone 1.62 an SHA1 hash was used by default for OnedrivePersonal. For 1.62 and later the default is to use a QuickXorHash forall onedrive types. If an SHA1 hash is desired then set this optionaccordingly.
As a rule of thumb if nearly all of your data is under rclone's rootdirectory (the root/directory in onedrive:root/directory) thenusing this flag will be be a big performance win. If your data ismostly not under the root then using this flag will be a bigperformance loss.
