This page allows system administrators to manage replications. You can create, edit, and delete replication tasks. You can also run/stop the syncing and view the information of your replication tasks.
For the best user experience, it is recommended to install the same version of Snapshot Replication on your source server and destination server.
You can create multiple replications for an iSCSI LUN to multiple destinations, forming a one-to-many scheme. You can also create an extended replication for a replicated iSCSI LUN, forming an extended scheme.
The maximum number of replication tasks varies depending on your Synology Unified Controller models. Please visit Synology's website for information about applied models.
This option provides an ideal solution to help you specify the maximum amounts of snapshot versions to save your volume space, but you may need to retain your snapshots for longer periods of time. There are a few things to note about Retention Policy:
Example 1:
If you want to keep daily snapshots for the past 3 months, weekly snapshots for the past 4 to 6 months, and monthly snapshots for the past 7 to 9 months, you need to input 0 for hourly snapshots, 90 for daily snapshots, 24 for weekly snapshots, 9 for monthly snapshots, and 0 for yearly snapshots.
Example 2:
If you want to keep hourly snapshots for the past 2 days, daily snapshots for the past week, weekly snapshots for the past month, and monthly snapshots for the past year, you need to input 48 for hourly snapshots, 7 for daily snapshots, 4 for weekly snapshots, 12 for monthly snapshots, and 0 for yearly snapshots.
