hello @tarmo888 @tonyofbyteball

[tarmo888]

This is most likely because corrupt database, which most likely happened because loss of power to full node.

Solution: restore earlier backup or restart syncing from scratch by deleting the database.

[backenders-game]

Thanks for response. I am trying to download full DAG data again

On the other side this is very bad user experience. Now i should download 4 days and 70gb. There should be a way to download missing or faulty chunks .

And it is not clear what to delete and what not from your response

[tarmo888]

You could also restore the seed words, but I think deleting rocksdb folder and sqlite files should work too.
This is not normal experience, it only happens when you machine stops unexpectedly, normally closing the app would not do that.
For best user experience, GUI wallet makes most sense as light node because it can store private data, which is easier to backup with light node.

If you want a full DAG database then I would suggest running https://github.com/byteball/obyte-relay, which is just a copy of DAG without any keys. If you wish, you can even use it as full node you can relay transactions from GUI wallet. That too is vulnerable to sudden loss of power, but it's easier to keep backups.

I don't really want full DAG, i want to keep my blackbytes from backup. It is possible only with full node, right?

[tarmo888]

you do not need full DAG for blackbytes, blackbytes are not even stored on DAG. you just need proper backup, not just seed words.

you just need proper backup, not just seed words.

Hello! How can i get a "proper backup"? To me available only seed or full backup. Full backup backuping all dag (wich i have only 10gb). Because of that when i restore from full backup, wallet starts synching to 50+ gb, wich is lasts too long.
How can i restore from full backup (i have 10 gb) if i want use blackbytes, but without download full dag?

[tarmo888]

@github4366 if you don't have any other private data (smart-contracts, multisig, attestation profiles) in the wallet other than blackbytes, then you could:

• restore the 10 GB backup file and then send blackbytes via message (this will create a blackbytes textcoin).
• delete the app data folder.
• start the wallet app and pick light node.
• restore with seed words.
• open the blackbytes textcoin to retrive the blackbytes from textcoin.
• make a new backup file (this time it would be a backup of light node).

If you have any other private data then you can't convert full node to light node like this because you seed words only restore public data.

@supernova2033 maybe you're confusing a full-backup of your wallet with full-backup instance of the whole DAG?

[tarmo888]

That could be because older versions of the wallet app called both (light and full node) backup files as full backups. Latest wallets call it "Backup all wallet data". Obviously, when making a backups, the latest wallet version should be used because there has been fixes to that process too, not just renaming.
