Backup process lock others out of DB?

I had a backup fail on PM run because of diskspace issue. Fixed that and ran
the job this AM. It just about crippled our DB, and my web-server couldn't
get data, just time outs.
Is this normal for the DB backup to override requests for data? If so are
there other backup software packages to create a .bak file instead of EM's
jobs?
TIA
__StephenNo, its not normal...were you writing to the same disk that the datafile(s)
reside on?

No I write to a separate server for all backups and transaction logs. I
didn't think it was correct either.
Actually my server was getting hammered with batch work at the time. It's
Tues. morning so lets try to batch in 20% of our weekly business. I do a
tran log backup every 15 min and the one this morning at the time things got
hairy was only 514 meg. Normally its in the 5+ meg range. So that massive
file is an indication that I'll be beating on my system hard for the next
hour or two. We are a print shop and we feed 3 Xerox doc-u-beasts doing
financial outputs and checks.
