Hi all,

I look to the mail that I receive after a backup procedure for a Windows SBS 2008 64bit and the results are:

This is normal? All the time I receive a succesful backup...but I'm not 100% sure about this!

Thnak you!
 
What is the output of

# vgs

and

# lvs

Please can you post that?

Is that a standard install or did you modify something?
 
Code: 
 vgs
  VG   #PV #LV #SN Attr   VSize   VFree
  pve    1   3   0 wz--n- 465.26G 4.00G
Code: 
lvs
  LV   VG   Attr   LSize   Origin Snap%  Move Log Copy%  Convert
  data pve  -wi-ao 352.26G
  root pve  -wi-ao  96.00G
  swap pve  -wi-ao  13.00G
Code: 
 pveversion
pve-manager/1.3/4023
It's a standard instalation from 0.9 (or 1.0 I think) updated all the time.

For backup I have mounted another 250GB disk.
 
Other backups are OK (for 2 XP 1 Vista and 1 Windows 2003 SBS). Only for this machine I receive these messages.

The disk is OK...in logs I don't see anything

How I can check the disk? Any advice?

Click to expand...

use a hard disk diagnostic tool (see the website form seagate or whatever you got) - or third party, using a live-boot-cd.
 
this is a backup result for onother machine on the same server:

no errors....

Maybe it's a size error? The SBS2008 machine have more then 75GB...
 
Hi All,

I come back with my fisrt conclusions; I make some investigations on both Hard Disk's but no errors found. Then I see that on backup disk was available less then 75GB. I delete some old backups from other machines and now the backup finish normaly.

Code: 
105: Aug 26 20:00:03 INFO: Starting Backup of VM 105 (qemu)

So, for people who receive simillar errors these was a first sollution. Check the free space on backup disk or backup partition.
 
HI All,

I realy don't understand what happen here! Why 3 days ago the backup was OK and after that...with error!
The hardware it's OK!
 
yes...but the error appear after 25 hours....this is the reason that I'm worry about the situation! Why?

Maybe the disk is full and totally fragmented?
Click to expand...

but why one time work correct and after that not...the disk is the same...and the space not change...

Now I will add another disk special for this backup...500GB...I hope will be OK.
I will post the results!
