# It will:
|
|
# 1. Shutdown BTCPay Server
|
|
# 2. Start bitcoind
|
|
# 3. Prune it to up to 289 blocks from the tip
|
|
# 4. Stop bitcoind
|
|
# 5. Archive in a tarball the blocks and chainstate directories
|
|
# 6. Restart BTCPay
|
|
# 7. If AZURE_STORAGE_CONNECTION_STRING is set, then upload to azure storage and make the blob public, else print hash and tarball
