Oracle Online Redo Logs

Veeam Logoby UT2015 » Tue Jul 18, 2017 1:22 pm

Hi there,

we are planning to backup a Windows Server system with an Oracle 12 database.

As far as I understood, Veeam is able to perform a full backup e.g. daily and is also able to backup the archive logs frequently. The smallest value according to some guides/screenshots seems to be 5 minutes.

Meaning in the worst case, we are able to restore from Veeam repository the latest "full backup" and additionally the processed archive logs. But in the worst case, the last 5 minutes (redo logs) would be missing.

Is it possible to also backup the redo logs into the Veeam repository? Should the redo logs be backed up to a different location?

It would be nice, if a complete backup without loss or with at least the smallest possible loss of data could be handled by Veeam B+R.

Best regards

Veeam B&R doesn't process online redo logs.

So as a conclusion, in the worst case 5 minutes processed data are gone when using Veeam to backup an oracle VM, correct?

Hi UT2015,

to come back to your question. Yes, Veeam will backup the Oracle redo logs to the same location where the VM backup files are stored. Log backups are storead as .vlb files.
