This spark a question, so a flashbackup is almost the same as a normal file level based backup which also able to retore individual files, wat are the cons of using flashbackup beside higher cost to buy the advanced client licenses? Anyone here knows the pros and cons?
Not only is the Flash backup faster, we've found that it consumes significantly less CPU than a "walk the file system" backup for file systems with a lot of files.
The largest con is that it will back up the full size of the volume for a full, whether the space is allocated or not. In other words, if you have only 1 GB of data on a 1 TB volume, you'll still back up 1 TB.
You can not suspend Flashbackups - once they start, you must either finish them or kill them off and start over. There is no checkpointing.
