Funny, we set ours down to 25% as well just to see what would happen. This worked but we have since set all of the ATA Pools to 50% and we just leave them there. Theoredically what could happen is we could be wasting twice as much space but the fact is the volumes were going from 25% to 50% in a matter of days and when we looked at how many volumes were between 25% and 50% in our enviornment we determined there was no need to reclaim down that far. From all outword signs there was no issues with reclaiming down to 25% we just didn't think it was worth doing the extra work to get back such a small amount of disk. Disk is cheap, right! lol

We are just piloting an all disk backup pool for some clients on one of our servers and for small files on another. -----Original Message----- From: Steve Harris [mailto:[EMAIL PROTECTED] Sent: July 26, 2004 6:26 PM To: [EMAIL PROTECTED] Subject: Re: D2D vs. tape backups with TSM? So, how high do you set your file class reclaim percentage? If its that fast you should be able to cope with 20% free or less before reclaim. Steve. >>> [EMAIL PROTECTED] 27/07/2004 9:12:33 >>> Dito and that is how we implemented large disk backup solutions on ATA disk. We use File device classes. We have found that the reclaim extremely fast, much faster than tape.

There are some other faster restore solutions out there. With Virtual Tape Libraries you get all the speed and reliability of D2D but with all the functionality of tape. For example, I happen to work for a company that provides a VTL solution which is certified by IBM-TSM. There is no way to run reclamation on D2D so that must be done once it is transferred to real tape. With a VTL solution, you backup to a virtual tape library and device, run the reclamation on that, which is nearly instantaneous and then copy to real tape via archive and that saves you hrs and hrs of reclamation time. The other benefit is the near unlimited amount of mount points. With backups and restores, the speed of real tape and libraries are not longer your bottleneck. --------------------------------- Do you Yahoo!? New and Improved Yahoo!
