snapshot location

Post by alex77t » Jul 29, 2019 8:08 am

Hi,

how can see where volume snapshots are stored for full machine backups?
I have a job that i stopped but want to make sure that local volume snapshot files are eventually removed.

thanks,
Alex

Hi,

If you grep these logs you can see where exactly the snapshot was placed:

Code: Select all

cat /var/log/veeam/Backup/<jobname/Session_<date>_<ID>/Job.log | grep veeamsnap
For example, I got this:

Code: Select all

[22.07.2019 20:08:58] <140207482177280> lpbcore|       Snapshot host device: 253:0, path on device: veeamsnapstore.{4601de08-b9ce-488d-98b7-c8184d251407}, fsuuid: 148345db-92ab-4f5b-b062-b3e1a48b1df8
I checked lsblk and it turns out that 253:0 is my root LV:

Code: Select all

[root@dhcp ~]# lsblk
NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
fd0               2:0    1    4K  0 disk

├─sda1            8:1    0    1G  0 part
└─sda2            8:2    0   15G  0 part
  ├─centos-root 253:0    0 13.4G  0 lvm  /
  └─centos-swap 253:1    0  1.6G  0 lvm  [SWAP]
sdb               8:16   0   16G  0 disk

sr0              11:0    1 1024M  0 rom
To check FSUUID use lsblk with -f:

Code: Select all

[root@dhcp ~]# lsblk -f
NAME            FSTYPE      LABEL UUID                                   MOUNTPOINT
fd0
sda
├─sda1          xfs               faa73925-50b5-439d-8d11-1c1241751d95
└─sda2          LVM2_member       ZsKXjr-2inR-foEd-7W3A-zwRn-dakz-nHVgDL
  ├─centos-root xfs               148345db-92ab-4f5b-b062-b3e1a48b1df8   /
Thanks!

thanks a lot for your prompt response, P.Tide

i've got these in the logs

Code: Select all

[28.07.2019 23:20:25] <139794349172480> lpbcore|       Snapshot host device: 9:3, path on device: /veeamsnapstore.{8ee2cb40-02d2-40ba-91c6-7e177e627eaa}, fsuuid: ad49559f-422f-44f4-a8d7-6b0ca7d09174

and it looks like it was trying to snaphot /home partition, and also tried to allocate 1.7Tb for the snapshot on the same partition in /home/veeamsnapstore.{8ee2cb40-02d2-40ba-91c6-7e177e627eaa}  ?

[28.07.2019 23:20:18] <139794349172480> lpbcore|     Requesting snapshot for device md2 [9:2].
so instead of doing full machine image, how would i back it up in this case ? Would it be possible to assign a different path to the snapshot? OR run it without creating a snapshot?

sudo lsblk -f

In your case the snapshot has been placed on /home partition. If you see any snapstore remnants there, then you should contact our support team.

If you want to specify snapshot location manually, you need to set location=/path/to/directory in /etc/veeam/veeam.ini file under [snapshot] section and reload veeamservice.

Thanks!
