View Full Version : size required

May 2nd, 2007, 01:07 AM
i have seen from the logs what actually zrm does at the backend and i have noticed that to take the backup of a particular database it first copies that database into temporary directory and then run tar or gzip over it.I just needed to know that if i do have a database of over 200Gb then do i need 400Gb space for its backup to be taken thru ZRM ? If yes then is there any way to escape it out.Kindly help.
Hoping a quick and positive response from ur side.

you can use --tmpdir option. Specify --tmpdir same as --destination this will ensure space required would be eventually the same

See the option at the end of the help o/p shown below.
