@florent said in Continuous Replication jobs creates full backups every time since 2025-09-06 (xo from source):
@Andrew @peo
are you using purge snapshot data ?
In both case, can you try disabling it and disabling CBT on the relevant VMs ?
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.
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.
Doing the replication to another host made it fast even when transferred in full.
CBT+delete = still "Backup fell back to a full" (this was the third since my XO update)
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)
