Just a quick question, can I copy the bitcoin core files from one drive to another and not have to re sync? I know I could just try but I’m out at the moment and thought I’d ask you guys to save the trial and error later.

Downloaded and synced at the weekend using one of my old NAS drives and this morning it started throwing up S.M.A.R.T bad sector errors... guess that’s why it was removed in the first place  Grin

Yes, you can. If you've fully synchronized the blockchain, the chainstate would've been assembled already. The pre-verified data directory can be copied from disk to disk and you don't have to synchronize again.

Yes, the only inconvenience is you need to wait few minutes (if you use old/cheap HDD) after copy whole database to different drive or run Bitcoin Core from different as Bitcoin Core OS will show message "Verifying blocks" for a while.

A bit off-topic, altcoin wallet which based on older Bitcoin Core might have problem, especially if you load it from different OS.

All back up and running now!

Another question, if I were to set up a node using a Pi3 could I copy this data again to the SSD I’m planning on using for that?

Yes. There are some people who run Bitcoin full nodes (along with LN sometimes) on Pi3

You might want to make sure your SSD have interfaces which Pi3 support

the blockchain can be copied and then used anywhere.

since its so big and my internet stupid slow that it would literally takes months to sync from genesis i regularly backup the whole thing to various offline harddrives and store them here and there (offsite as well) as well as the automated rightly backup to a raid nas at the house.

just be sure you have your wallet well encrypted if thats in the backup too.

a separate backup on a disconnected external drive saved me months of syncing one time when the blockchain on the daily driver got corrupted and that propagated to the nas backup too before i caught it. so do rolling or incremental backups to local nas (so you can roll back to a good copy) if automated nightly backups are your thing.

although that satellite broadcasted blockchain looks like is really worth looking into. im really wanting to pull the trigger on that.
