Worked example – backup, replication and housekeeping overlaps

Because we have sized D2D2502 for the sources - there is a limit of 4 concurrent source replication jobs at any

one time.

This simulation is valid for Code Versions 2.1 and above which use container matching technology and

improved housekeeping performance.

Start of Replication Window

Spare Time for future growth or Physical Tape Offload

Housekeeping Window

During a rotation scheme cartridges/shares are being overwritten daily, so housekeeping will happen daily.

Consider Sites A and D

In the example below housekeeping is happening when other backups are running and also when replication is

running.

Initial Configuration with NO replication blackout window set

There are many overlapping activities (housekeeping and replication running together) and performance is not

predictable.

There is no real control. Backups are

overlapping with replication and

housekeeping leading to unpredictable

results.
