Solr在Google Cloud上备份和还原

Question

I have been struggling in getting solution for below scenario:

• I have 2 instances of solr cloud on composite engine.
• I have 2 instances of application rest api which calls above solr cluster for data.
• From my application I wanna take backup of solr and copy zipped backup file to google storage automatically and restore it automatically with the an url endpoint.

For that I am trying to make a api endpoint in my application that will call below solr api to take back up

admin/collections?action=BACKUP

And making another endpoint that call below url to restore

/admin/collections?action=RESTORE

However after taking backup my application doesnt have access to the back up files as they are getting saved on solr instances. So I am not able to save them to google bucket.

Please guide me a simpler way to achieve this ie automatically backup and restore solr from other GCP instance.

Answer 1

Have you considered something like gcs-fuse ? It'll allow you to mount a GCS bucket directly on the file system.

You can then point the BACKUP command directly to the mount point for gcs-fuse on your Solr compute engine VMs, and the whole thing is abstracted away through how the VM is configured (instead of having to be manually uploaded afterwards with a separate tool when a local copy has been made).

Answer 2

我发现GCSFuse有点不可靠，因此决定编写一个包装脚本，该脚本首先检测给定集合的主服务器，然后直接在该节点上执行备份。
