Restful API - restore mailbox as .pst for big mailboxes

[olekl]

The issue/question is related to this API call: https://helpcenter.veeam.com/docs/vbo36 ... tml?ver=40

In case mailbox is big (let's say, 40 GB - for enterprise mailbox it is quite usual) the exported .pst is preparing during hours on VBO, and then it is transferred back via http response in one piece.

Even if you set EnablePstSizeLimit to True, all pieces of .pst are archived to one file before sending back, so you still have transfer of one big piece.

And I don't thing that transfer of 40GB which is trying during hours without any progress indicator and without possibility to restart in case of any network issues is a good idea.

So the question: what is the expected way to do a restore big mailbox as .pst?

Support ticket: Case #04190048

Hi Oleksandr, it is true that via the API call, the process runs in the background. If you want to benefit from it, you will need to build a sort of download handler which starts the export in the background and lets the user of the portal/tool know once it is done. You could consider storing it in a s3 bucket or something as a temporary location.

Yes, it already runs in the background and user is informed when it is finished. There are two issues: 1. we can't estimate time of waiting (it could be 20 hours or more) and 2. we can't restart it in case of any network interruption (40 GB+ transfer without restart option could never succeed).

Wondering if there's been any updates to this item, or if anyone else has run into these issues and has a work-around?

Hi Brad,

No updates so far. The issue is on our radar, but I can't provide you any ETA on when to expect the fix.

Hello,

We have the same issue here. I have check api v5 and I don't see changes for the api to restore pst file.
Does this fix is expected for the v6 ?
thanks

Hi Nicolas, as Polina stated there is no ETA for this but your request is counted.

Hi All,
i was wondering. did Exporting Large PST (More than 2 GB) works fine using Rest API? .
If so, anyone have a living example of this.
as it seems any downloads handler or clients are stuck on receiving the response from Veeam Side.

[nielsengelen]

Hi Mohammed, no changes on this topic. The proposed workaround (use some location to export it to and validate if a file is there) would still be relevant.

Hi,
do you mean that Exporting Large files using Rest API doesn't work?
so how to export the files correctly?
