Are there any freely available recent snapshots for the main net that I could download ? I'm looking for either full or rolling.
TzDutch has been providing recent backups of the chain since the beginning of betanet called quicksync. This service has proven to be trustworthy and invaluable to a lot of new node operators. They now have an import friendly version also since the introduction of snapshots.
Update: TzDutch is shut down and sadly, quicksync is no longer available. I recommend using Tezosshots, they are newer but trusted source run by an active community member.
You can already get full mode snapshots here.
Alphanet Archive and Mainnet Archive coming soon™.
Automated full and rolling snapshots available here: https://github.com/Phlogi/tezos-snapshots
