Cloud Catalyst sync_to_cloud tool
Abstract
Description
The sync_to_cloud tool is designed to be run on a CloudCatalyst server. It will upload to the cloud any MSDP container and catalog files in the CloudCatalyst cache that have been modified since they were last uploaded.
Product Version:
All versions of NetBackup Cloud Catalyst
Problem Description:
This tool will primarily be used as one of the premigration steps to prepare a CloudCatalyst server for migration to MSDP Cloud. Specific information about those steps will be included in the documentation for the migration procedure.
This tool can also be used to repair a CloudCatalyst server that has gone down because the cache has become full. It is possible for CC cache to become full if
there are too many files that have not been uploaded to the cloud and CloudCatalyst will not evict any files from the cache that have not been uploaded.
When the CloudCatalyst server is down, there are no active backup or duplication jobs to trigger the upload of these files to cloud so the cache remains full and the CloudCatalyst server stays down.
This scenario is rare but it can occur when the upload bandwidth to the cloud is too small to accommodate the amount of data being written to CloudCatalyst by backup or duplication jobs (i.e., the inbound bandwidth).

Tool Installation and Execution Instructions:
- Download zip file
- Extract sync_to_cloud and put it on the CloudCatalyst server
- Make certain all NetBackup services are up and running on the CC server.
- Make certain that NO SLP or backup or optdup jobs are or will be running when the sync_to_cloud process is started. Running backups or duplications to the CC server while the script is running could cause conflicts.
- Execute sync_to_cloud as root
# ./sync_to_cloud
Note: Execute sync_to_cloud in such a way that it can run for a long period of
time without timing out. For example, use nohup or some other method that
will allow the command to continue even if you are disconnected to the system.
If there are TBs of data to upload to the cloud from CC Cache, that process
can take a lot of time depending on available bandwidth.
6. Monitor the /usr/openv/netbackup/logs/esfs_storage log file for "Upload is done" messages.
7. The output from the script will be in the /usr/openv/esfs/log/ops/sync_to_cloud directory. There will be one sync_to_cloud.<pid> output file and one upload_results.<pid> output file.
Sample output (small system, not representative of amount of output for production system):
