Stellar start downloading ledgers from the begining

hocok_b_kapmahe

I've run stellar-core with COMPLETE_CATCHUP=true.

When it synchronized to 3151488 block (it took about 4 days and it's only 15% of full blocks) I've just need to reboot the server (the electricity in the house was gone)

And now, when I set CATCHUP_RECENT=lastledger - 3151488

stellar-core just started from the begining! It's not actually write to the db all data from the begining. It download buckets from 0% but leaves data in stellar-db untouched
Why it downloaded data from the internet if we have it on the stellar-db ???
Also ! I conf file I've set a history that stored on local disk ! What this "history" for ?

So now I need to wait 4 days again ???

Also. when I will have fully synchronized stellar db with horizon, and when I need to reboot it, than stellar will start downloading ledgers from the begining and I've got a outdated stellar-db for a weeks? Cool ...

It's a normal?

Sorry for my English.

hocok_b_kapmahe You said that you synced to block 3151488. CATCHUP_RECENT=lastledger - 3151488 would not continue from 3151488. CATCHUP_RECENT means that "at least CATCHUP_RECENT number of ledger entries will be present in database" (also make sure you remove or set the CATCHUP_COMPLETE to false otherwise the CATCHUP_RECENT is ignored)

If you started your core with CATCHUP_COMPLETE=true and your core stopped (power outage etc) you just need to start it again without changing anything in the config and it would continue where it was before.

In case you are using the docker image make sure that you are using persistent storage for /opt/stellar directory. Otherwise every time when you restart you loose the DB and the archive.

One way to make sure that your stellar-core does not re-download all the history from the internet to catchup from scratch is to use stellar-archivist and download the archive locally. Then you just need to copy this archive into a folder that the stellar-core is using for archive (in docker quickstart this is /opt/stellar/history-cache)
