+12Hi, I need a clarification regarding a sizing for an Oracle backup (RMAN Plug-in) with on-prem object storage.
As per best practice when I configure a backup on Object Storage I use an Incremental Forever chain without Full (active or Synthetic).
On calculator, in Policy input, I cannot set 0 (zero) in “Full backup per week”.
Considering these settings, I imagine the chain stored, how calculator works, is as standard chain with weekly fulls. Is correct?
Thanks
+12Hi
As this is actually not a Veeam backup but an RMAN backup driven to a Veeam repo via an enterprise plugin, you have different rules here regarding the retention.
RMAN has the concept of full DB backups (Level 0) followed by incremental backups (Level 1) and optionally redo-log backups. But those incrementals are never run forever as with Veeam image level backups because no merge operations exist here. You would have to keep an infinite chain.
Thus, you have to have a full every once in a while. Usually, my customers do a full at least every week or sometimes even every day in the evening. This complemented by incrementals each day and of course redo-log backups (e.g. every 10min.).
Hope this helps,
Michael

If I use this repo for VM Backup I have no discussion (Incremental Forever without Full) but I don’t know what happens with Oracle DB backup (I add a bit… DB are encripted withe TDE) in an Object Storage.
+12Encryption won’t be a problem IMHO - in contrast to dedupe appliances.
But you will not see any “dedup” between the fulls. Each full is “fully” independent. Also compression, with the enterprise plugin backups, depends on your settings in the plugin and/or RMAN as both can do compression optionally and only one of them should do at the same time.
