12 hours is extreme, we take backups of 10TB worth of indexes in 15 mins using the collection backup api. How are you taking the backup?
Do you actually see any backup progress or u are just seeing the task in the overseer queue linger ? I have seen restore tasks hanging in the queue forever despite process completing in Solr 77 so wouldn’t be surprised this happens with backup as well. And also observed that unless that unless that task is removed from the overseer-collection-queue the next ones do not proceed. Also adding replicas while backup seems like overkill, why don’t you just have the appropriate replication factor in the first place and have autoAddReplicas=true for indemnity? > On Aug 10, 2020, at 6:32 PM, Ashwin Ramesh <ash...@canva.com.INVALID> wrote: > > Hi everybody, > > We are using solr 7.6 (SolrCloud).
