For information about the remote server requirements, see Backup Server Requirements.

After that, backups are incremental.ĭo not modify the backup files. The first backup of Assurance data is a full backup. The Assurance data consists of network assurance and analytics data. You can back up automation data only or both automation and Assurance data.Īutomation data consists of Cisco DNA Center databases, credentials, file systems, and files. You can use the backup and restore functions to create backup files to restore to aĭifferent appliance (if required for your network configuration). Example of NFS Server Configuration-CentOS.Example of NFS Server Configuration-Ubuntu.Set this to '*' to allow requests from any hosts to be proxied. Set this to '*' to allow the gateway user to proxy any group. To allow the hdfs user to be a proxy for all other users, add the following entries to core-site.xml on the NameNode: Configure the user running the gateway (normally the hdfs user as in this example) to be a proxy for other users.For example, if an application uploads 10 files of 100MB each, should have roughlyġGB of free space to allow for a worst-case reordering of writes to every file. Make sure the directory you choose has enough space. Memory for any given file, they are dumped to the (the memory threshold is not currently configurable). After these out-of-order writes have exceeded 1MB in Reorders writes, and so sequential writes can arrive at the NFS gateway in random order and need to be saved until they can be ordered correctly. This directory is needed because the NFS client often You should change the location of the file dump directory, which temporarily saves out-of-order writes before writing them to HDFS.
