Hi, I have no tested to backup on cloud solr and restore on a standalone solr but I believe it can works to.
We use that: https://solr.apache.org/guide/7_3/collections-api.html#backup https://solr.apache.org/guide/7_3/collections-api.html#restore With a custom script that make a backup for the collections we want it, and after we can restore on demand. One thing if you have multiple solr instances the backup and restore must be in a NFS filesystem, shared by all the instances servers. Test it and tell us! Luck with it! Kind regards. ________________________________ David Martín Nieto E-mail: [email protected] | Web: www.viewnext.com ________________________________ [https://mail.google.com/mail/u/0?ui=2&ik=72317294cd&attid=0.0.2&permmsgid=msg-f:1662155651369049897&th=171129c229429f29&view=fimg&sz=s0-l75-ft&attbid=ANGjdJ_o0Ds8_P8d7W-csq2mmc6mBGQy9hSjXsGEv15RXUutalCYzg3HQB3CByE2swcJkH3yRaLwrXkr1G81F9FpfqcPlbpRoZcainmsJjviLoypusuKOxCnOw97zuo&disp=emb] ________________________________ De: michael dürr <[email protected]> Enviado: miércoles, 6 de julio de 2022 15:32 Para: [email protected] <[email protected]> Asunto: Howto restore backup from solr cloud to solr standalone after upgrading to 9.0 Hi, we have a production environment that runs solr in cloud mode and we have a testing environment that runs solr in standalone mode. From time to time we use a database dump of our production environment and import it to the testing environment. Since it would take too long to build the solr indices on the testing system afterwards, we do the same with the production indices, i.e: As we don't have any sharding, we simply create a snapshot backup from the production environment, copy it to the testing environment, and restore that index from the snapshot as a solr core. Afaik solr 9.0 no longer supports the old snapshot backup (incremental=false) What is the best way to keep that workflow going after upgrading to 9.0? Thanks! Michael
