rsync without a checksum check? Centos 7
Hi All,
I am trying to perform an rsync without a check sum verification at the end of the copy. I have tried both the -W (whole file) and the --no-checksum option and at the end of both file copies it performs a verification. Code:
[root@centsrv01 /]# nice -n 20 rsync -avz --no-checksum --bwlimit=2000 --progress /opt/vidconvert/converted/testfile.mp4 /opt/RouterUSB/TV/ChromeCast/ I am copying from an XFS filesystem to a NTFS (CIFS) file system to a Samba share. Unfortunalty NFS is not an option. Any Ideas? Thanks |
rsync by default updates based on date of modification + size change. But yet it verifies transfered files using checksum.
There is also a non default option of checksum. With it sending and receiving files are checksummed in their respective systems and if they don't match then only the files are updated. |

But based on what you've posted, what verification are you seeing, where?? All I can see is rsync sending a file...was that file already present? Quote:

I have read rsync man page. Well TBOne the rsync man page says it uses checksum in various steps. And question was about confusion regarding checksums happening even with no checksum option.

Again, this has to do with the differences in file systems, and the OP hasn't actually said how they reached that conclusion, did they? |
