Hi everyone, I'm trying to evaluate the capabilitiies of bareos, and see how it integrate with netapp storage. I'm not a backup/storage expert so regarding my current knowledges I have some problems to fully understand some parts of the documentation. So please, feel free to correct me on everything that seems wrong to you.
My starting point was to see how data may be deduplicated. As I understand, bareos has file level deduplication, but not block level dedup. So it tried to see if block level deduplication was possible to gain some storage space (in case we want to backup some big files with common parts, as I imagine that VM disk images could be). I know that NetApp storage support natively block level deduplication (and compaction, compression). So I tried to understand how bareos write it's data to the storage backend to understand if block deduplication could work on the NetApp storage. I took a look at Storage Media Output Format <https://docs.bareos.org/bareos-19.2/DeveloperGuide/mediaformat.html#storage-media-output-format> part of the doc but it becomes a bit more tricky for me to figure out if block dedup could work here. In addition, I suppose that if the data is encrypted this could make block deduplication useless. I also took a look on internet and I just found a bacula document: https://blog.bacula.org/whitepapers/DedupVolumes.pdf They seems to talk about filesystem that supports deduplication, and specific configuration about "Aligned Volumes". So, could bareos be configured in a way to better use netapp storage capabilities as block level deduplication ?
