Use encrypted transmission: If you choose to use encrypted transmission, you will have to enter
the other host’s SSH connection information in addition to your Rsync account information.
Use 1 on 1 folder synchronization: If you decide to use 1 on 1 folder synchronization, all the
data in the designated destination folder will be synchronized with the data in your source folder
(you may only select one folder). The contents of both folders will be exactly the same. If you decide
not to use this feature, all your chosen source folders (you may select multiple folders) will be copied
one by one to the destination folder.
Keep extra files at the destination: Once the copying and synchronization of files is completed,
the data at the source and destination should be exactly the same. However, sometimes there are
extra files present at the destination. These files are only present at the destination but not at the
source. By enabling this option, these extra files will be kept at the destination and will remain
untouched.
Archive mode (incremental backup): 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 3.2.9 Rsync Server.
