Backup Copy - Change time between retries?

Post by mrholm » Sep 17, 2018 10:24 am

Hi
We do a lot of bakcup copies over WAN to StoreOnce Catalyst. Sometimes a VM i failing in a job and Veeam retry that VM but StoreOnce then have the files locked and we get 1909 OSCLT_ERR_OBJECT_LOCK_FAILED and the job will fail after 5 retries.
Can we change the time between the retries as we can for backups? If yes how long will StoreOnce keep the file locks nowdays?

Here is info ir: b/u copy job retries:
https://helpcenter.veeam.com/docs/backu ... tml?ver=95

These retry intervals are 'automatic' and are not configurable in the GUI. You may be able to make a change to this via Registry, but I'm not 100% sure. You may be able to get an answer from Veeam Support about that being a possibility or not.

Regards.

Hi Mats, in older StoreOnce versions the file lock period was indeed long. What SO version do you have?

We're using 3.18.3 on our StoreOnce.
If it's like you say that the file lock is down to 20 min it's still long for 5 retries in Veeam copy. It must be a way to change the retry in copy as it is in backup jobs??

Please try the BackupSyncMaxRetriesPerOib registry value.

Foggy, what does the registry setting, you mentioned, change?

The number of data transfer retry attempts. Actually, there are several types of retries and which one you need depends on the reason of the initial job failure:

When doing copy to StorOnce we get OSCLT_ERR_SERVER_OFFLINE 1404 nd since Veeam tries a restart directly without timeout the next try get OSCLT_ERR_OBJECT_LOCK_FAILED.
We like to set a timeout between retries in copy job as I can for bakcup jobs

Have you tried the registry setting? Increasing the number of retries should help to cover the file lock period.

Sadly the proposed workaround is not working and I open a new case 03247180.
This could not be such a "biggie" when it can be done in the bakcup jobs?
A big future request if this can't be fixed....

I'd also look for the ability to change the file lock period on the storage side, if possible.

I do agree but changing the file lock period on StoreOnce is not something for me to handle, believ ethat it would be easier for Veeam+HPE to look into this and solve the mechanism around this.

We seem to have solved the most WAN related errors so we see less of the errors associated with StoreOnce but I stil lthink that Veeam should be able to set intelligence on the backup copy since we point out that the repo is a StoreOnce Catalyst. Setting a timeout in the code or add the same possibility to set amount of retries and timeout between retries like in backup.

Btw, how StoreOnce is connected to Veeam B&R here - is it FC or iSCSI?
