I'm doing ftp copy(mirroring) with rclone.
I'm used to commanding as below:

but, The following error must be occured.

" Failed to copy: 451 Transfer aborted. Broken pipe"

It seems to automatically try 3 times at once command.
Some files succeed, but some finally fail.

How to reduce "451 Transfer aborted errors" or avoid the errors on rclone?

I would try with wget using the -c (=continue) option and see if it's better.

Do you mean I would use wget?

I can't put it much clearer, but YES I suggested you to try wget instead of rclone.

Ok.

I will try wget.
Could you tell me the command of wget for ftp mirror?

One has to figure out some things for oneself, newbie!
wget

I know already that.
Please let me know the example command for mirror.

You need to spend time reading 'man wget'

The default behaviour of wget --mirror' is to mirror the website, instead of some sub-directory and you may not want that. There is also some config file ~/.wgetrc.

As you're on the learning curve with linux, there's some learning to do. Be prepared to learn; the best way to do that is by reading, not asking.

Or, if preferred, there's HTML and PDF versions at https://www.gnu.org/software/wget/manual - which can be easier to read and search.

The best way to learn varies between different people, and whilst trivial questions are better answered by reading (or watching videos), this is a forum for asking questions.


wmk7032: When asking any question, it's important to identify what has been tried and where you're stuck.

The wget manual should have suitable examples - if there's something you don't understand, reference the part(s) you're looking at and say which bits aren't making sense, and it'll be easier to help.

You should generally read (at least) the "overview" and "invoking" manual sections of any software you hope to use, to ensure it'll work for the task you want and to get a minimal understanding of the tool.
