All of my backups work (now), and speeds range between 5 MB/s to 20 MB/s.

Most of my VM's are smaller (zstd helps a lot), though the largest archive is about 80 GB.

Also, all of my backups are sequential -- I seem to remember a previous note where somebody had problems with concurrent uploads.

My XOCE VM runs with 12 GB, which was the number that "just works" according to some of my earlier problems (and I haven't bothered to chase down or fine tune further).

The transfer rates were ok early in the sync process but eventually the speed dropped off into the 20 to 40 KBs speed. I'm guessing this is where XO would give up.

Wasabi was fine for small VMs, but not really feasible for my whole environment (40 VMs some as large as 1-terabyte).

I did notice that backing up larger VMs via XO to Wasabi (100 GB or more) would time out and fail between 60% & 80% complete. Small VMs were not a problem.

Thanks for the feedback

Can you define slow?

XO's support for Amazon was sufficient.

The proper AWS endpoint was crucial. As is your access key and secret key.

create a bucket, then create a folder under the bucket. Give XO the bucket name and the folder name.

The caveat is my backup speed is slow.
