It really depends on the type of data. Backing up VM images via rsync is slow because they always have relatively small changes in the middle of large files. Backing up large mail spools can be slow as there's a significant number of accounts with no real changes as well as a good number of accounts with only small changes (like the power users who have 10,000+ old messages stored and only a few new messages at any time because they delete most mail soon after it arrives). But even for those corner cases rsync will work if your data volume isn't too big. For other cases it works pretty well. I guess you have to trade off the features of using one filesystem everywhere vs the ability to run filesystems independently of what applications will run on top. I like the freedom to use whichever filesystem best suits the server. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list luv-main@luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
