NewTimestampedCheckpointFileName returns a string of a new checkpoint filename with a suffixed version.

ReadBackupCheckpointManifest reads and unmarshals a BACKUP-CHECKPOINT manifest from filename in the provided export store.

ReadBackupManifest reads and unmarshals a BackupManifest from filename in the provided export store.

ReadBackupManifestFromStore reads and unmarshalls a BackupManifest from the store and returns it with the size it reserved for it from the boundAccount.

ReadBackupManifestFromURI creates an export store from the given URI, then reads and unmarshalls a BackupManifest at the standard location in the export storage.

SanitizeLocalityKV returns a sanitized version of the input string where all characters that are not alphanumeric or -, =, or _ are replaced with _.

TempCheckpointFileNameForJob returns temporary filename for backup manifest checkpoint.

ValidateEndTimeAndTruncate checks that the requested target time, if specified, is valid for the list of incremental backups resolved, truncating the results to the backup that contains the target time.

WriteBackupLock is responsible for writing a job ID suffixed `BACKUP-LOCK` file that will prevent concurrent backups from writing to the same location.

WriteBackupManifest compresses and writes the passed in BackupManifest `desc` to `exportStore`.

WriteBackupManifestCheckpoint writes a new BACKUP-CHECKPOINT MANIFEST and CHECKSUM file.

WriteBackupPartitionDescriptor writes metadata (containing a locality KV and partial file listing) for a partitioned BACKUP to one of the stores in the backup.

WriteDescsSST is responsible for writing the SST containing the Descriptor and DescriptorChanges field of the input BackupManifest.

WriteFilesListSST is responsible for constructing and writing the filePathInfo to dest.

WriteMetadataWithExternalSSTs writes a "slim" version of manifest to `exportStore`.

WriteTableStatistics writes a StatsTable object to a file of the filename to the specified exportStore.

BackupFormatDescriptorTrackingVersion added tracking of complete DBs.

BackupLockFile is the prefix of the file name used by the backup job to lock the bucket from running concurrent backups to the same destination.

BackupManifestCheckpointName is the file name used to store the serialized BackupManifest proto while the backup is in progress.

BackupManifestChecksumSuffix indicates where the checksum for the manifest is stored if present.

BackupMetadataDescriptorsListPath is the name of the SST file containing the BackupManifest_Descriptors or BackupManifest_DescriptorRevisions of the backup.

BackupMetadataFilesListPath is the name of the SST file containing the BackupManifest_Files of the backup.
