Provided are techniques for managing backup operations from a client system to a primary server and secondary server. A determination is made at the client system of whether a state of the data on the secondary server permits a backup operation in response to determining that the primary server is unavailable when a force failover parameter is not set. The client system reattempts to connect to the primary server to perform the backup operation at the primary server in response to determining that the state of the data on the secondary server does not permit the backup operation. The client system performs the backup operation at the secondary server in response to determining that the state of the secondary server permits the backup operation.

Provided are a system and article of manufacture for merging metadata on files in a backup storage. A query is received for information on files from a file system for a client node. A determination is made of metadata for files in a backup storage for the client node stored external to backup sets. At least one backup set in the backup storage for the client node is processed to determine metadata for files included in at least one backup set. The determined metadata for files in the backup storage and for files included in at least one backup set is merged to form merged metadata. The query is executed against the merged metadata to determine files whose metadata satisfies the query. Results including information from the merged metadata on the determined files are returned.
