 If you don't see any running coalesce jobs, and can't find any other reason that XenServer has not started one, you can attempt to make it start a coalesce job by rescanning the SR. This is harmless to try, but will not always result in a coalesce. Visit the problematic SR in the XOA UI, then click the "Rescan All Disks" button towards the top right: it looks like a refresh circle icon. This should begin the coalesce process - if you click the Advanced tab in the SR view, the "disks needing to be coalesced" list should become smaller and smaller.

-### Preparation
 
-1. create a cont. rep job to a non-distant SR (even the SR where the VM currently is). Do NOT enable the job during creation.
-1. manually start the first replication (only the first)
-1. when finished, export the replicated VM (via XOA or any other means, doesn't matter how you get your XVA file)
-1. import the replicated VM on your distant destination
-1. you can now remove your local replicated copy
+### Job creation
 
-### Modifications
+Create the Continuous Replication backup job, and leave it disabled for now. On the main Backup-NG page, note its identifiers, the main `backupJobId` and the ID of one on the schedules for the job, `backupScheduleId`.
 
-In your source host:
+### Seed creation
 
-1. Get the UUID of the remote destination SR where your VM was imported
-1. On the source host: `xe vm-param-list uuid=<SourceVM_UUID> | grep other-config`.
-  * You should see somewhere in other-config: `xo:base_delta:<SR_UUID>: <VM_snapshot_UUID>;`
-  * Remove this entry with `xe vm-param-remove uuid=<OriginalVM_UUID> param-name=other-config param-key=xo:base_delta:<SR_UUID>`
-  * Recreate the correct param: `xe vm-param-set uuid=<OriginalVM_UUID> other-config:xo:base_delta:<destination_SR_UUID>=<VM_snapshot_UUID>`
+Manually create a snapshot on the VM to backup, and note its UUID as `snapshotUuid` from the snapshot panel for the VM.

+
+### Set up metadata
+
+The XOA backup system requires metadata to correctly associate the source snapshot and the target VM to the backup job. We're going to use the `xo-cr-seed` utility to help us set them up.
+
+First install the tool (all the following is done from the XOA VM CLI):
 
 ```
-xe vm-param-set blocked-operations:start uuid=<DestinationVM_UUID>
+npm i -g xo-cr-seed
 ```
 
-### Enable

+Usage: xo-cr-seed <source XAPI URL> <source snapshot UUID> <target XAPI URL> <target VM UUID> <backup job id> <backup schedule id>
+
+xo-cr-seed v0.2.0
+```
+Putting it altogether and putting our values and UUID's into the command, it will look like this (it is a long command):
+```
+xo-cr-seed https://root:password@xen1.company.tld 4a21c1cd-e8bd-4466-910a-f7524ecc07b1 https://root:password@xen2.company.tld 5aaf86ca-ae06-4a4e-b6e1-d04f0609e64d 90d11a94-a88f-4a84-b7c1-ed207d3de2f9 369a26f0-da77-41ab-a998-fa6b02c69b9a

+### Finished

+## SUDO
+
+If you are running `xo-server` as a non-root user, you need to use `sudo` to be able to mount NFS remotes. You can do this by editing `xo-server/.xo-server.toml` and setting `useSudo = true`. It's near the end of the file:
+
+```
+useSudo = true
+```
+
+You need to configure `sudo` to allow the user of your choice to run mount/umount commands without asking for a password. Depending on your operating system / sudo version, the location of this configuration may change. Regardless, you can use:
+
+```
+username ALL=(root)NOPASSWD: /bin/mount, /bin/umount
+```
