We can't seem to get reliable transmissions of backups to our BackBlaze B2 bucket. After sending for a while, we get an error "Failed to send request post https://pod-000-1099-09.backblaze.com/b2api/v1/b2_upload_file/..._t0024: HTTPSConnectionPool(host='pod-000-1099-09.backblaze.com', port=443): Max retries exceeded with url: /b2api/v1/b2_upload_file/..._t0024 (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))
We're running on ESXi v5.5, patched to current. Ideas?

Can you run ./vertical -vv --log backup vm_name and post the output here (or email to vertical-backup-support@acrosync.com)?

I've emailed a DropBox link to the address above. Thanks for your help!

Oh, and if I try to restart the backup again with the same command line, it fails with:
2018-01-19 18:41:14.493095 INFO BACKUP_LISTING No previous backup found.

It looks like the B2 upload server rejected the connection. I don't know why, but you can increase the number of retries by setting VB_MAX_RETRIES to 16. The default is 8, but if it is a connection error, the number of retries is half of that.
For the memory error, you can run the backup command as:
./vertical backup --no-chunk-listing vmname
With this --no-chunk-listing option, Vertical Backup will not attempt to list all chunks in the storage and construct a chunk cache in memory. The downside of this option is that for each chunk that already exists in the storage, a lookup is needed to determine if the chunk upload can be skipped.

I'm probably doing something wrong here, but I get a "error: unrecognized arguments: --no-chunk-listing" error when I try that option. That option also doesn't show up for ./vertical backup -h. Am I running the correct version (1.1.5)?

If you download the latest 1.1.5 build from http://acrosync.com/esxi/vertical it should have this option. The sha256 of the latest build is 11a9459a2a93047d16fe5e9399186c33f383e8843ac19b601527cc543eb897bf.

The Guide page has the wrong link on it then. Thanks.
