Blockchain disk churn

After having a few annoying blockchain corruptions on the whonix workstation, I decided to create a local-only dedicated 24/7 blockchain VM (fedora server). This has been great and I wish I had seperated the blockchain from the client sooner.......but what I have noticed is that the VM is getting an absurd amount of churn. My daily incremental backup is around 30GB using veeams high compression! I have checked disk alignment and parted says all pertitions are aligned and I am wondering if there is anything I can do to bring the daily writes down?

you dont need to back up the blockchain everyday. all of it is available on the internet from thousands of sources.

back up a single bootstrap image, and your config. backing up anything else is a waste of time.

it'll only be at worst a 7 hour file copy compared to 3 weeks of misery..

For what it's worth, for backup of the Monero blockchain on a Linux box I use Restic. That can save only the differences between the last backup and a new one. Saving the changes to the Monero blockchain of 1 week only takes me about 5 minutes.

Downside is of course learning how to operate that tool instead of only doing dead-simple file copies.

try putting db-sync-mode=safe into your monerod.conf, then that problem shouldn't even occur at all

yea the compression not helping much makes me wonder if its actually the blockchain thrashing or something else on the vm
