very slow copy on mount of WindowsXP shares - was Re: copy onto cifs-utils samba mount maxes out at 100KiB/s on 100Mib/s eth link
I realised my subject belied a little misunderstanding on my part. cifs-utils is now separate to samba. cifs-utils provides for kernel mount of windows (or samba) shares. Again, here's my command (all one line): $ sudo mount -t cifs -o file_mode=0666,dir_mode=0777,setuids,credentials=mycreds //server.ip.address/git /x When I copy files from the /x/ mount to the /x/ mount, or within (both from and to) the /x/ mount, it is extremely slow, in the order of 100KiB/s I'll see if I can hunt up a fuse option and test that.

Slow copy
Hi, This is perhaps one of the stranger questions to be asked but I'm looking for a utility that will copy a file slowly. Part of my ad hoc backup system is to copy the nightly backup tar file from our production machine onto another machine. The problem is that the production machine is not exactly what you would call high performance and the file copy basically causes everything else to grind to a halt. It doesn't matter to me that the copy is done in 5 minutes or 50 minutes what matters is that it doesn't kill the server for 5 minutes a day. What I am basically looking for is a version of cp with a max copy rate argument. I would write my own but I can't believe that I'm the only one who has ever wanted this feature so I suspect there is one already in existence.

It may not alleviate the slowdown of the production machine but it would shorten the time of transfer; rsync only copies changed files. It would however require backing up the files themselves rather the tarfile. I put up some notes on backing up a file server using rsync with some links I found really useful: http://www.clivemenzies.co.uk/selfhelp/FileServer_Install_manual.html Regards Clive -- www.clivemenzies.co.uk ... ...strategies for business -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I have wanted this every time I had to try and salvage data from flaky hardware. Running cp or scp or rsync at full-speed would lock up the system. I'm not aware of any solution, though, short of creating a new program or modifying cp. -D -- Q: What is the difference between open-source and commercial software? A: If you have a problem with commercial software you can call a phone number and they will tell you it might be solved in a future version. For open-source sofware there isn't a phone number to call, but you get the solution within a day. www: http://dman13.dyndns.org/~dman/jabber: [EMAIL PROTECTED] signature.asc Description: Digital signature
