What is the problem you are having with rclone?
I recently uploaded ~800gb of data to Jottacloud using encryption and base 32 encrypted file names, but Jottacloud has a 255 character limit on file names and some of my files exceeded the limit, so I tried to do a server-side copy and re-encode the file names in base 32768.
The first time I attempted to do this, I got no errors in the terminal when running rclone copy crypt: crypt-base32768: --server-side-across-configs, and it appeared to work correctly. However, in my encrypted-base32768 directory, there were two sub-directories, and one of them worked fine while the other didn’t.
When I tried to download a random file from the broken directory, I got a file not found error. Running rclone lsf crypt-base32768: worked and showed all files correctly, but running rclone lsf crypt-base32768:/broken-directory-name errored, with something like “directory [name] not found, maybe it’s a file?" (I don’t have the exact message now, sorry).
I also got this error when attempting to open the broken directory on the Jottacloud website:
I thought perhaps Jottacloud doesn’t support these file names, so I contacted their support and they said that base 32768 file names should work correctly, and that they ran some tests and everything appears to be working, and that I should test with the official jotta-cli program. I created a test directory containing thousands of files that had the same names as all the files and directories in my encrypted-base32768 directory, and it uploaded them all successfully.
I deleted the crypt-base32768 remote and the encrypted-base32768 directory and tried to recreate them again, but now when I run the same copy command as above, I get a few errors like this:
2025/10/23 14:52:02 ERROR : [unencrypted-file-name]: corrupted on transfer: sizes differ src(Encrypted drive 'crypt:') 130454936 vs dst(Encrypted drive 'crypt-base32768:') 0
and then several thousand errors like this:
2025/10/23 14:52:02 ERROR : [unencrypted-file-name]: Failed to copy: parsing time "1-01-01-T00:00:00Z" as "2006-01-02-T15:04:05Z0700": cannot parse "1-01-01-T00:00:00Z" as "2006"
