    I had scheduled consistency checks to run on an AWS S3 bucket weekly. I didn't notice for two weeks until my S3 storage ballooned to 3 times the size it had been previously.

    After researching, it looks like when the scheduled consistency check ran for the first time, it cleared all entries from the local database. The next time the backup ran, it uploaded the same files that were already in S3 storage. The next week the scheduled consistency check ran and the same thing happened. I synchronized the repository to S3 and confirmed duplicate file name entries in the cloud_files and cloud_file_versions tables. The data is indeed duplicated in S3.

    I manually cleaned up the duplicate entries in S3 using an inventory report to remove objects uploaded on dates the backups ran after the consistency check. Then I synchronized the repository, which sync'd the local database to the S3 bucket.

    Then I backed up the database to have a rollback option and manually ran a consistency check. The local database was cleared again. Below are sample entries from the logs.

    There are thousands of these entry types. I've confirmed the file is stored in the S3 but I have not researched to determine the file details to try to map the data back to the cbb repository.

    I've run consistency checks in the past without issue and am unable to figure out what has changed. Based on this behavior, I do not plan on using this feature again.

    I will rollback to restore the most recent backup prior to the most recent consistency check and assume all is well, since the local db has been sync'd with S3.

    Can someone explain exactly how the consistency check works, or is supposed to work?

    Can someone explain why the consistency check is clearing data from the local database?

    Thanks in advance for any assistance with this issue.

    Consistency check just verifies that data on storage is consistent with the selected for backup source data.

    I assume you are using legacy backup format, which is a low maintenance mode. Have you considered New Backup Format instead?

    Hi Alexander. I appreciate the response but I don't think you understand my issue. Did you read through the details? I am using legacy backup jobs.

    I've been using Cloudberry Backup since 2017 and have had no issues with consistency checks that I'm aware of. Beginning recently, consistency check will delete all entries in the cbbackup database and data stored in the S3 repository is unaffected. The next time a backup runs, duplicate files are uloaded to the S3 repository, I assume because Cloudberry Backup has no knowledge of files being stored in the S3 repository since there is no data in the cbbackup database for the destination.

    I'm able to reproduce this issue on demand:
    - Navigate to Backup Storage for the repository. Browse and restore various files to the local file system, confirm the restored files files are valid.
    - Run a Consistency Check for the repository. Wait for the Consistency Check to complete
    - Navigate to Backup Storage for the repository. The repository shows as empty. No files or folders are displayed for browsing.
    - S3 storage is unaffected.

    The consistency check is doing more than simply comparing the local repository toe S3 storage and reporting differences:

    Log files show these entries as part of the Consistency Check. All entries are deleted for the destination. 1001 is the destination id for the S3 repository affected.

    This is most likely a software regression after one of the recent updates. This might be fixed with the next release. If you send me your contact email address in DM I can give you a pre-release build to test.
