Hello,
I have windows 2008R2 with SQL 2008R2 and a database of 4.3Tb, I use CR successfully (for 2+ years now), I do the transfer on a LAN link in http mode.

For a transfer on a 1G LAN, you will have a transfer time of 60-72 hours. You must set in XCP-ng the time to kill the task for 72 hours minimum, in /etc/xapi.conf line 306 set: pending_task_timeout = 259200 # 3 days in seconds.

For a transfer on a 10Gb LAN you will have a transfer of 7-14 hours.
I don't use snapshot with memory but the recovery was ok, I had an event.

Can you put an extra message at the Full backup interval, which will display what step it is until the next Full backup.
For example, as in the photo below, the first is the current one and the second is the desired one.

original one

with the desired modification

Thank you

For me is ok with fixTasks branch

Backup Delta always refers to the last Full Backup. So the ones before the Full Backup can no longer be restored on a backup made after them

It is working for me to, thank you

Fallow the steps from here

@julien-f said in Error importing vhd or VM:

[http.listenOptions]
requestTimeout = 0

With this setting, it works in both directions - import and export. I am on commit 817911a41eecdb3cc8a72db5f290ddacdd4f9873

I didn't have time to test it, I will test it tomorrow

Edit:
I couldn't resist and I tested. Commit 817911a41eecdb3cc8a72db5f290ddacdd4f9873
VHD and XVA export is ok now.
But the import doesn't work, at XVA the log is below,
at VHD it's just this:

Import
NetworkError when attempting to fetch resource.

XVA

XOCE commit d7da83359f007236784f2644213b288e24759823

I can't modify a Pool metadata backup, I get the error below.
I can create it without problems, but I can no longer modify it.

Hello,
I have windows 2008R2 with SQL 2008R2 and a database of 4.3Tb, I use CR successfully (for 2+ years now), I do the transfer on a LAN link in http mode.

For a transfer on a 1G LAN, you will have a transfer time of 60-72 hours. You must set in XCP-ng the time to kill the task for 72 hours minimum, in /etc/xapi.conf line 306 set: pending_task_timeout = 259200 # 3 days in seconds.

For a transfer on a 10Gb LAN you will have a transfer of 7-14 hours.
I don't use snapshot with memory but the recovery was ok, I had an event.

Backup Delta always refers to the last Full Backup. So the ones before the Full Backup can no longer be restored on a backup made after them

I chose ext4, precisely so as not to waste unnecessary space

base copy it's the reference, it's that vdi that contains all the information before snopshoot.
If you use the LVM format it is normal to be like this, if you use the ext4 (vhd) format it will only be the difference.
Because you don't have space, use the ext4 format for SR

I tested the same thing with XCP-ng 8.3, it seems to work. I can't wait for it to be ready for production. The first impression is very good.

Ok, thank you

I have a virtual machine with the following configuration: sda - with OS, sdb - with data and sdc - hdd usb attach. As in the photo below.

And I want to make a backup only to sda and I receive the era below. How to configure the backup so that I don't have this error?

It is working for me to, thank you

@arsenieciprian.
For me all backups are working now, except that one. And that I split it into 2 simple backups
