I'm no rsync guru my any means, but two things spring to mind. Use the -t option to stop all the spurious check summing. Split your script into multiple scripts, each with a share of host names. Run each in parallel. Multiple rsyncs can run on the one box concurrently. Craig -Original

differential backup using deltas.

I was wondering if the following is possible, or is planned for rsync. I backup a number of databases with rsync that work very well with the rsync algorithm. Ie, I am backing up a gigabyte+ database over a dial-up speed link and it doesn't take very long, so the daily differences in the files

This probably won't help, but I had a similar problem with rsync 2.6.9. Cwrsync with rsync 2.6.9 on Windows 2003 server to OpenBSD. (rsync 2.6.8, not using daemon mode) 2.6.8 at both ends worked perfectly. Upgraded to 2.6.9 just on the Windows box and it would just hang at a diffent spot each

RE: Backup Exchange mailboxes using rsync

I do an offline copy of the exchange database, but (as you indicated) as it can be tricky to use on another server, as seconday backup I use EXMERGE to extract everyones mailbox to a PST file. I then rsync the PST files. It has some limitations, but it works ok as a secondary backup. I've used

changing bwlimit at runtime.

I am using rsync in a situation where the amount of bwlimit I want to use changes depending on the time of day. for example, I startrsync at 2am when no-one else is using the system, so I want it to use100k/sec. At 9am, it is still running, but as the bandwidth of the link it's using now

exclude an excluded file from being deleted by --delete-excluded

2006-02-08 Thread Craig Hammond
Hi, I have a particular directory in my exclude list, but I want it excluded from --delete-excluded. Is this possible. or maybe if I explain what I'm trying to do, someone will come up with a more suitable way. I am using rsync (2.6.6) to backup data from a Windows Server (cygwin) to an OpenBSD
