Hi Matt, Thanks for your fast reply!
Yeah, that would be an option too. I can pass rsync the files to use as basis files. I'll take a look at the feature enhancement. Your option with monolithic will work also, but will require a huge amount of freespace on the destination server. I have got 18 customers who use this option for Disaster Recovery and already need 1.5TB+ of fast storage. If I rsync with monolithic files I probably need to have 1TB+ of freespace on the SAN and that's kinda expensive....

Specific support for VMware split images would be way too special-purpose to justify putting it in the main version of rsync. A more general option to make each file transfer use multiple basis files (or even all the existing destination files) may be reasonable. You could join this enhancement request, which I might then reopen: https://bugzilla.samba.org/show_bug.cgi?id=5954 But in this scenario, why are you using a split image? Does it have some advantage over a monolithic image (with which rsync would Just Work)? -- Matt -- Please use reply-all for most replies to avoid omitting the mailing list.
