Can I eliminate diagnostic messages from cp

Can I eliminate diagnostic messages from cp

[lostbits]

I use cp as my backup tool from disk to USB. There are maybe 40,000 
files involved and each one has a message of
"cp: preserving permissions for <file>’: Not supported". These messages 
slow down the backup and obscure meaningful faults. Is there any option 
for removing the messages?

My command line is: cp <directory> /<usb>

thanks
art

Umm, add command line flags that don't request the permissions to be set?

E.g.,  --no-preserve=mode

You can play around with the various options of preserving / not preserving
mode, ownership, date/time, etc.

If your USB is formatted in FAT, then --preserve=none will get rid of these
messages.
As FAT doesn't really support anything at all.

cp --preserve=all is documented as suppressing operation not supported
messages, and cp -a (archive) is documented as suppressing messages about
inability to preserve information which can not be stored on the target
filesystem.

Alternatively, instead of using the default USB DOS/VFAT format, you could
format the USB drives as NTFS, which would allow cp to preserve the
ownership and ACLs on the files.
