After enabling this feature, successive backup jobs (after your first backup job) will only copy the
data that has changed since your last backup job (block level). For example, if you have made
some small changes to a 10 MB file, incremental backup will only copy the portions that you
have made changes to. This can significantly reduce bandwidth usage.
Compress data during the transfer:
During backup you can compress the data that is being transferred thereby lowering bandwidth
usage.
Keep file metadata:
When you enable this option, certain file properties (permissions, extensions, attributes, owner,
groups, etc.) will be sent along with the file to the destination.
Support sparse files replication:
You will only need to enable this option when the data that you wish to back up contains sparse
files. Normally, you will not have to enable this option.
Mission Mode:
Sometimes backup jobs may be stopped because of various connection problems with a busy
server on the other end. ASUSTOR's Mission Mode option allows you to configure the number
of connection attempts and time interval for connection attempts, ensuring for the successful
completion of your backup job. This also gives IT administrators a significant amount of
flexibility when configuring backup jobs.
Reminder: If you wish to use Remote Sync while using your NAS in conjunction with another
remote ASUSTOR NAS, please remember to enable the Rsync server feature on the remote
NAS (Services -> Rsync Server). For more information please see Rsync Server.
