are you using purge snapshot data ?<br />
In both case, can you try disabling it and disabling CBT on the relevant VMs ?</p>
</blockquote>
<p dir="auto">Yes, I was using CBT + purge snapshots, but that might not have been the reason for the sluggish transfer speeds with the later versions of XO.</p>
<p dir="auto">I discovered that the SSD on my destination host were going bad, a write of a /dev/null-filled test file (1GB then 5GB) on the device started at expected 450MB/s, but slowed down to less than 10MB/s. Found a bunch of unexpected errors (because the disk was more or less new) in the logs by dmesg.<br />
Doing the replication to another host made it fast even when transferred in full.<br />
CBT+delete = still "Backup fell back to a full" (this was the third since my XO update)<br />
CBT w/o delete = first backup=full transfer (4 min) and garbage collection (a few more minutes), second=delta transfer (a few seconds backup time)</p>

this can happens after a failed transfer, a new disk added and some edge case. This issue was not really visible before the latest release, even if the impacts can be important , saturating network and storage.</p>

<p dir="auto">But, during testing I found a new related issue (no error messages). Running current XO master b16d5...</p>
<p dir="auto">During the normal CR delta backup job, two VMs shows the warning message: <code> Backup fell back to a full</code> but it did a delta (not full) backup.</p>
<p dir="auto">I caused this by running a different CR backup job (for testing) that used the two same VMs but to a different SR. The new test job did a full backup and delta backup correctly. Since there is only one CBT snapshot the normal backup job did recognize that the snapshot was not for the original normal backup job and should have done a full (and started a new CBT snapshot), but it only did a short delta.</p>
<p dir="auto">As the VMs were off, I guess it could correctly use the other CBT snapshot as no blocks had changed... Just odd that CR backup said it was going to do a full and then did a delta.</p>
