| + | * Once required minimum hotfix version is applied, as a one-time routine the next backup job will automatically remove Blocks (BAK) from the Destination containing backup files that reference invalid checksum file chunks, then reupload source backup file that was corrupted and correctly update the migrate status table. A flag will be set in the Index to denote fix was applied ( likewise reverting the Index to an older copy will retrigger the fix ). [Shared Blocks (BAK), a block containing multiple small source files (valid and corrupt), won't be purged until all contents of shared block has cycled through changes and surpass Retention period.] | ||
