Re: Holding Disk Question
2002-08-15 15:10:33
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
