Rsync failed: Invalid argument (22)

Hope everyone is doing well!

Thanks to everyone in Rsync, Unix and Linux, for their great work, and thanks to everyone willing to help, I appreciate it, means a lot to me!

I am using rsync to syn around ~2TB of data.

I get the following errors in the log file:

rsync: [receiver] mkstemp "/mnt/sd25-4tb-bkp4-mnt4/tns-maindatads-smb/tns-maindatads-smb/main-data-subds-1/GoogleDrive-alk8915-bkp-2024-07-09-1800/Programirane neshta failove alk19890105/SoftUni/SoftUni AI 2021 Materials/SoftUni - AI - Data Science June 2021/softuni-ai-datascience-2021-project-FINAL-SUBMISSION/softuni-ai-datascience-2021-project-atkuzmanov-FINAL/resources/images/.Icon#015.pu2lTm" failed: Invalid argument (22)

I researched around for this error, but everywhere I found related to ownership, which should not be my case, as I am using --no-o and --no-g.

I think it is probably related to some special symbols, such as new line or “:” (colon).

I definitely have some files and directories which contain “:” (colon), they are system files and I want to be able to synchronize them without renaming them as this will cause problems. How can I do that?

Here is the rsync sync command I am running with the flags:

rsync -avvvzh 
  "$SRC" 
  "$DEST_DIR" 
  --log-file=$log_file 
  --progress 
  --links 
  --checksum 
  --bwlimit="192M" 
  --delete-during 
  --delete 
  --timeout="60" 
  --compress 
  --no-o 
  --no-g
