i have six datastore with each one have one replica JOB.
In the first replica JOB i have 3 VM and only in VM3 when arrive to step "Applying Retention policy" the task is very slow, it take about 5 hours!!!
All datastore is in the same HP SAN.
In the email activity i can see this technical information:
Code: Select all
Success Start time 20:00:07 Total size 665,7 GB Backup size 48,9 GB End time 02:33:48 (+1) Data read 273,0 GB Duration 6:33:40 Transferred 81,3 GB Details Name Status Start time End time Size Read Transferred Duration Details VM1 Success 20:01:35 20:56:17 135,7 GB 133,7 GB 1,9 GB 0:54:42 VM2 Success 20:56:22 21:12:40 60,0 GB 4,0 GB 2,1 GB 0:16:18 VM3 Success 21:12:46 02:33:39 (+1) 470,0 GB 135,3 GB 77,3 GB 5:20:53
During the first 30 minutes of "Applying Retention Policy" i receive the alarm of Veeam One about disk latency warning and after resolve automatically
How can i troubleshoot my issue?
Why only in this VM it takes so long time to this step?
