Compression and deduplication for raid-based datastores

[Leo David]

Hello,
It might be a noob question, but its not very clear for me:
- In case of creating datastores that is placed ontop of a RAID ( 1,10 ) arrays, will the stored information be compressed / deduplicated, or these features are only available for zfs-based datastores ?

Thank you,

Leo

both compression and deduplication are storage-agnostic in PBS.

Hi Fabian. And what about Remote sync to another PBS Server?

also completely independent of the underlying storages on either end

WOW really? How do you manage the delta sync? I thought you use the ZFS sync?

compare snapshots existing on either end, then only download those indices and chunks which are missing on the pulling side.. since we can check for existence of up to 4MB of logical data with a single stat, this is fast enough.

This is a very neat feature, and really helps a lot.
Thank you for such a great product !
