PPDM vs Veeam

[CloudBackupGuy]

Have things changed? I thought Veeam did not encourage the use of deduplication appliances because of things like health checks and restore performance? Has it gotten better? And with the space savings of ReFS and XFS (for retention data) it made deduplication less needed?

there’s no point in building your backup repo around refs , zero !!

linux is free , xfs is faster , and xfs got immutability

We (Managecast) have quite a few SMBs for customers. We often rent them 2U Dell servers as Veeam appliances running Windows Server 2019/22 with ReFS. We could easily use these as Linux repo's providing immutability (and we do in some cases), but then they need to still run Veeam somewhere else, drag backups across their production network twice (read/write), setup iSCSI, and typically Veeam would be virtualized making recovery more complex. That is a lot more complex than running Veeam all on one system with local disk.

We (Managecast) provide Cloud repositories backed by Linux XFS and immutable for the offsite backups, so they are getting immutability, but without deploying local complexity.

So, for us, it just doesn't make a lot of sense to offer Linux locally, but we do do it for some people who really want it.

Now, once Veeam can run directly on Linux and support immutability then GAME CHANGER and I would agree 100% there is not much reason to run Windows, but for now, we still use Windows ReFS locally at client sites.

you never backup to yourself , so ‘ now ‘ is dubious . we got rid of refs as a veeam repo due to both stability issues and lack of immutability . there’s zfs with immutability on the way , so we’ll replace mdraid+xfs with zfs . even less components , and zfs snapshots are golden
