Hi,
One of my clients is using SQL server 2005 and have been doing sql backups of huge databases (50GB). there is a total of 800 GB of different databases in that server.
Normally a full backup of those databases will take around 2 hours.
Lately for some unknown reason, the backups taking forever (~14 hours). I suspect the disk performance, but did chkdsk and looked for bad sectors and end up confirming the disk is fine.
I did a read write test by checking resource monitor which shows while doing sql backup read write speed is ~20 to ~ 30 mb/sec which is really the problem. But the bizzare finding is that when I copy and paste a file across to the same backup directory the r/w speed is ~200 mb/sec.
I am baffled at this stage and got no idea where and what is gone wrong.
Thanks
RD
