>My motto: Disk is cheap, don't skimp on holding disk. > Yup... after I deployed a 181 GB drive for our holding disk, I saw somewhat different behavior in amstatus... though I would have expected the total time of the backups to drop (compared to a relatively small 25 GB holding space I used before) they did not... I conclude this was because the entire run is tape i/o bound... Holding disk usage on the runs with this disk were about 90% capacity... so the clients were not taking so long to complete their data transfers...
This would seem to indicate I need to double this amount of space to hold 2 days of backups, currently... I'd like to have a week's worth, actually.... in case the tape goes South and replacement is not easy and quick. So does the chunksize parameter affect performance in any way? thx --
