GitHub user markusm0815 created a discussion: Backup VMs with NetWorker -
unparsable date
Hello everyone,
we are trying to backup VMs with DELL EMC NetWorker like explained in the
documentation, but we get an error in Apache CloudStack:
2026-05-06 11:35:52,629 ERROR [o.a.c.b.B.BackupSyncTask]
(BackgroundTaskPollManager-6:[ctx-2a868e38]) (logid:88d9e389) Failed to sync
backup usage metrics and out-of-band backups of VM [VM instance
{"id":2661,"instanceName":"i-12-2661-VM","state":"Running","type":"User","uuid":"6c912cc4-97ea-4a89-9fe5-dc4843e743ef"}]
due to: [Unable to parse date [2026-05-06T08:29:55Z].].
com.cloud.utils.exception.CloudRuntimeException: Unable to parse date
[2026-05-06T08:29:55Z].
It looks like the backup itself is working correctly, but when CloudStack tries
to read the backup details it cannot parse the date from the NetWorker.
It seems, that the datetime from NetWorker includes the time-offset
(time-offset = "Z" / time-numoffset), but Apache CloudStack expectes the
datetime without the time-offset:
SimpleDateFormat formatterDateTime = new
SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");

Is this correct? I'm not sure if my conclusion is right.
I've seen that there are some discussions about NetWorker, has anybody
experienced this too and/or a hint what we can do?
Versions:
Dell EMC NetWorker: 19.14
Apache CloudStack 4.22
Thank you for your help.
