If I'm not wrong, with fideduperange, kernel performs comparsion check before dedupe. And it will increase time to dedupe files. I believe the risk involved with ficlonerange is minimized by having a backup file(reflinked). We can revert to older original file, if we encounter some problems. > > -- > Have a nice day, > Timofey. Cheers. Lakshmipathi.G
