ReadyDR: Backup Options
Bandwidth Limits help ensure that ReadyDR does not over-saturate the network, affecting performance of other clients using the network (especially when transmitting to another ReadyNAS over the internet).
The default value is 0 KBps, meaning that there is no limit set.
Enter a value in kilobytes to set a limit.
Note: When performing a local to local ReadyDR job on a lower-end ReadyNAS device, you may need to enable bandwidth limits if you experience slow performance while ReadyDR is running.
Compression is applied to the ReadyDR job using an lz4 algorithm.
Compression has three options:
- Disabled: disables compression.
- Better: provides a higher compression ratio, but results in more CPU usage. Should be used on smaller network pipes.
- Faster: provides faster transfer, but results in a low compression ratio.
Note: Compression is disabled on a local to local job.
ReadyDR can transmit data between ReadyNAS devices with encryption, if desired. The data is not encrypted once it reaches the destination.
By default, Encrypted Transport is disabled.
Note: Encrypted Transport is unavailable on local to local jobs.
Export seed for this job
Seeding exports all currently existing snapshots from a share/LUN to a file, then requires importing the seed file to the destination ReadyNAS, avoiding an initial large network data transfer.
When Export seed for this job is checked, the ReadyDR job will be disabled after creation to allow for importing the seed.
You can export the seed to a USB or eSATA device, or leave the seed file in a share for later use.
When you're ready to import the seed from the source ReadyNAS, navigate to the Admin Page of the remote unit, click the Backup tab, click the gear icon on the destination job, then click Import.
After seeding, resume the job by clicking the gear icon on the source ReadyNAS and select Enable. From this point on, ReadyDR will start backing up incremental changes from the most recent snapshot to the oldest snapshot until the ReadyDR share matches the source share's snapshot layout.
If the source share is already configured for a custom snapshot schedule, ReadyDR will allow that custom snapshot schedule to be used. Otherwise, ReadyDR will help you set a snapshot schedule it can work from (hourly, daily, or weekly). ReadyDR cannot help you configure a custom snapshot schedule. To configure a custom snapshot schedule for ReadyDR to use, modify your share's snapshot configuration from the Shares tab.
There are two types of backup schedules, Instant and Periodic.
- Instant Backups send the snapshot immediately after it is taken.
- Periodic Backups sends any snapshots taken at scheduled times.
If the snapshot isn't taken before the scheduled run, it could potentially miss that snapshot and wouldn’t send any more snapshots until the next schedule. Plan ahead: if the snapshot is supposed to take at midnight, don’t schedule the job for midnight, too. Schedule it for the next hour.
