I asked Perforce tech support the same question, and was told that if pt4d gets through the checkpoint without crashing or hanging, then the database is OK.

By the way, here are the scripts I use for daily backup on NT. If you see anything wrong, or a suggestion for improvement, please let me know:

daily.bat: --- cut here --- @echo off d: cd \Perforce set P4USER=xxx set P4PASSWD=xxx call daily1.bat 2>&1 | smtpmail -h xxx.xxx.xxx.xxx -s "Perforce daily" gkasten --- cut here ---

daily1.bat: --- cut here --- p4 verify -q //... p4 verify -q -u //... p4d -jc -z tar cf - depot | gzip95 > depot.tar.gz rmdir /S /Q DayBeforeYesterday move Yesterday DayBeforeYesterday move Today Yesterday mkdir Today move *.gz Today df -k -P --- cut here ---
