Method Detail

shouldBackup

boolean shouldBackup()

Checks if a backup needs to be made.

If a call has not made any change, e.g. an AtomicLong increment with 0, no backup needs to be made.

Returns:

true if a backup needs to be made, false otherwise.

getSyncBackupCount

int getSyncBackupCount()

The synchronous backup count. If no backups need to be made, 0 is returned.

Returns:

the synchronous backup count.

getAsyncBackupCount

int getAsyncBackupCount()

The asynchronous backup count. If no asynchronous backups need to be made, 0 is returned.

Returns:

the asynchronous backup count.

getBackupOperation

Operation getBackupOperation()

Creates the BackupOperation responsible for making the backup.

Returns:

the created BackupOperation responsible for making the backup.
