NAME

plakar-check — Check data integrity in a Plakar repository

SYNOPSIS

DESCRIPTION

The plakar check command verifies the integrity of data in a Plakar repository. It checks the given paths inside the snapshots for consistency and validates file macs to ensure no corruption has occurred, or all the data in the repository if no snapshotID or location flags is given.

In addition to the flags described below, plakar check supports the location flags documented in plakar-query(7) to precisely select snapshots.

The options are as follows:

-concurrency number

Set the maximum number of parallel tasks for faster processing. Defaults to 8 * CPU count + 1.

-fast

Enable a faster check that skips mac verification. This option performs only structural validation without confirming data integrity.

-no-verify

Disable signature verification. This option allows to proceed with checking snapshot integrity regardless of an invalid snapshot signature.

-quiet

Suppress output to standard output, only logging errors and warnings.

EXAMPLES

Perform a full integrity check on all snapshots:

$ plakar check

Perform a fast check on specific paths of two snapshot:

$ plakar check -fast abc123:/etc/passwd def456:/var/www

DIAGNOSTICS

The plakar-check utility exits 0 on success, and >0 if an error occurs.

0

Command completed successfully with no integrity issues found.

>0

An error occurred, such as corruption detected in a snapshot or failure to check data integrity.
