First, you should be using a much larger split size than 10M -- you are wasting a lot of time and tape space with files that small. Assuming your tapes are ~60G, I would recommend somewhere around 1-3G. > Problem is amrestore doesn't close 10M files it already restored (can see it > using lsof) and after some time, I hit the system limit for open files.

If the files are being restored in order, then amrestore should close the files when it "reassembles" them. If this is not happening, you can use the -r flag, and then use dd to strip off the headers and concatenate the results. > Btw, is there a way to rebuild indexes from tapes? Amfetchdump has a -i option to do this. I'm not sure it was present in 2.5.1. Dustin -- Open Source Storage Engineer http://www.zmanda.com
