Is chcksum necessary when copying files through SFTP?

What is the problem you are having with rclone?'

Some files get stuck at 100% when copying files through SFTP. Adding --ignore-checksum flag makes it work without a problem but from what I read I know the files could be currupted, I just thought sftp has its own checksum so rclone could be not needed? Would using another software such as nextcloud or syncthing be better than rclone? My only goal is only to transfer files from a server I used to rent to my unraid server. Thanks for the help

Run the command 'rclone version' and share the full output of the command.

- os/version: slackware 15.0+ (64 bit)
- os/kernel: 6.1.79-Unraid (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.22.4
- go/linking: static
- go/tags: none

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

Not a cloud storage but a seedbox I am I have been renting for a while. I have now built my own server and would like to transfer my files to my new server.

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

 rclone copy host: destination: -P --checkers 5 --log-file /mnt/user/files/logs/copy-log.log -v --transfers 5

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

@T_A

the files could be currupted

that is true for any type of commutation, digital or analog.
most modern protocols use https, which does basic check-summing.
i believe sftp lacks that.

perhaps i could share a real-world example.

you posted currupted which should be spelled corrupted
a spell checker would have caught that error in transmission from your brain to the forum.
that is why i always use a spell checker and why i always use checksums.

on the flip side, if the source is non-critical, such as pirated media files, maybe not worth the overhead of checksums.
