Can not restore Stash backup (system.zip missing)

Question

We have created a Stash 3.0.1 backup using stash backup client 1.9.0 on Windows. When we tried to restore it on a CentOS machine, the restore failed with

stash-20150519-104526-716.tar could not be restored. Reason: /data/stash-data/system.zip (No such file or directory)

(/data/stash-data/ is my home directory, where I try to restore to)

I enabled DEBUG logging for the backup client, but it did not provide anything additional that seems useful.

Full log:

I have checked the backup file, and it indeed does not contain any system.zip, despite being huge (27GB). What is this system.zip file and what could be reason for it gone missing?

I know this is an old thread but this is at the top of Google results for this issue. I have just experienced a similar issue.

The system.zip seems to contain the database backup so is rather important.

In our case when we checked the tar file generated by the backup client the system.zip had a file size of 0b.

This was using version 3.3.3 of the client with a 4.8 instance of bitbucket server.

Short of taking a new backup there isn't much that can be done.

Hi Regius,

We've seen this problem happening on this bug report:

* https://jira.atlassian.com/browse/STASH-3987

It surprises me though you said the backup is from a 3.0.1 instance.

If you backup an instance that is 2.7.5+ or 2.8.3+ with the latest backup tool, that shouldn't happen.

Can you make sure of that and, in case you can't solve it, raise an issue with us? https://support.atlassian.com.

Best,
Thiago
