The complete answer can be found within *Unix**Backup* & Recovery. By W. Curtis Preston, ISBN: 1-56592-642-0 The short story is: depends. To backup web servers, dump will do online during the night, given you can live with the occasional file not backed up ('cause it changes while it's written). To backup mission-critical boxes, you have to get creative: mirror the disks, break the mirror, backup the offline disks; have a DB dump, get oracle to do its backup job... there are many possibilities. dump & restore work on online volumes too. Files which are not open will get backed up all the time, open files only if they do not change during the backup.
