Veeam backup

Post by jamerson » May 01, 2013 9:56 pm

Dear All,
is it possible to configure the Veeam to do the back just for the changes that been done?
i don''t want to back up the same files everyday,

thank you

If you’re talking about backing virtual machine, then please be aware that VB&R put into use special VMware feature called CBT, which allows us tracking/backing ip only those blocks that have been changed since the last backup run.

Moreover, even if CBT doesn't work, VB&R leverages its proprietary mechanism that works this way: VB&R scans through the whole VM image and a checksum (hash) is calculated for every data block, then it verifies what blocks have been changed on your VM compared to the VM image stored in the backup file.

So, in case of virtual machine backup/replication, it's practically always about an incremental not a full run.

If you’re talking about Copy Job, then you need to know it just transfers files as a whole knowing nothing about changes that have happened previously. So, it can be utilized in incremental way.

Hope this helps.
Thanks.

thank you for your answer,
yes i am talking about the files, as i have like 1,5 TB and it will take long to back it up every night,
so i want to run Full backup onces during the night, and schedule a job to back up the data ( i want this job to check just for the files that been changed to back them up, not the whole 1.5 TB, over and over every night,


thank you

Julien, this cannot be done with this kind of job. File copy job performs a full run every time.

If you need incremental backups, you can use ordinary backup jobs against the VM to copy just those blocks that have been changed in the VM guest OS since the job's previous run. Veeam B&R is a block-level solution and tracks changed blocks, not files.

If your files dont change , then the underlying blocks are not going to change either - so the CBT incremental will be pretty small. I have a customer who backs up a 2TB fileserver every hour; it takes 5 minutes and produced pretty small incrementals.

i dont mind having it every hr backing up,
but the issue it create a new folder,and double the files and folder,
so i want it to back up just to one folder,

I'm not sure I follow you there - you have a process within the VM that is duplicating a lot of files that you dont actually want to back up ?

Veeam backup creates a folder on the target per backup job and an additional file per job run.

my story is the next,
i have FS, DC, EX,
DC is 40GB
EX= 140GB
FS=1,5TB

FS= is 4 Partition, 1OS, 2 Data, 3 Backup, 4 BackupOS
i want to clone the VM machines just the OS ( C: ) to Backup OS on the File Server 4 Backup OS.
EX and DC clone the whole Server to the BackUp OS Partition,

Not sure why you want to back up to a partition on the same server? Sure you can add the partition(Disk) as a repository but what if you lose the server and need to recover? this will add further steps to you process, ie mounting the disk to another server re adding the repository to veeam.

I believe the question is not about Copy Jobs, but rather about Veeam backup jobs according to the later post below:

EX and DC clone the whole Server to the BackUp OS Partition,
So getting back to the original question - on every subsequent backup/replication job run Veeam will backup only changes that occurred on your VMs, no special job configuration is required.

Everyone on the official evaluation period is eligible for technical support, so feel free to contact them. This will be more efficient then using the forum correspondence.

Not a solution indeed, but still could be a viable workaround in some cases. What is your support case number?

Hi Julien,

Symantec requires in-guest agent and file index created during backup to enable file recovery, which is a completely different technology which cannot be compared directly with Veeam B&R. We perform agent-free image-level backup (one of many reasons why customers prefer Veeam to Symantec), and thus we have to be more creative at restore time.

However, as somebody from my team already explained you in another thread you posted this issue in, this is scheduled to be addressed in v7. Support is correct that the current limitation sits is outside Veeam code, but we should be able to work around it by redesigning some part of file level recovery engine.

The issue happens in pretty exceptional cases (very long file paths) and did not plague too many customers, which is why it was not fixed in earlier releases.

Thanks!
