Backups on Antsle One appliances

Hi, do cloud backups on Antsle one appliances take advantage of rsync so that each backup tracks delta changes and minimizes uploading?

Thanks

Hi Good Samaritan:

Although rsync isn't being used, both self-managed and cloud backups take zfs snapshot and compress with gzip format.

For example, my 1GB Debian LXC antlet was compressed to around 222MB for self-managed and cloud backups.
