Backup Time Suddenly Increases 50%
We have a NetBackup 7.5 system that backs up about 150 virtual servers and a dozen physical servers. One of those physical servers (call it Server X) has about 2.9 terabytes of data on a SAN. We do a weekly full backup and daily incrementals. Up until two weeks ago, the backup time for Server X was about two days. Starting two weeks ago, backup time suddenly jumped up to three days. There have been no significant changes to the server, and no changes to the NetBackup system. All the other backups are proceeding normally. What should we look at to determine why this particular backup job is taking so much longer? Server X is a Windows 2003 R2 machine. Thanks. -G.
