I am having some issueswith Volume Shadow Copy and our nightly backup - Event ID 20 and 8193. The backup seems to be ok despite the errors. The errorsgo away after a couple days. We see this happen about once a month. Would someone pleaseexplain further what the followingis telling me or offer some guidelines to troubleshoot this. We have plenty of room on the HD - C 30ttl/10 free, D 82ttl/70 free. SBS 2003 SP2 running Exchange, Exchange data on D. Thank you.
