问题
Recently I installed Nexus Repository 3 in OpenStack Cloud and I am using it for a while now. I would like to perform incremental backup of Nexus and thus securing our data.
How can one perform incremental backups of nexus data?
回答1:
The procedure for Nexus backup is described in documentation.
Nexus provides the scheduled task Export configuration & metadata for backup out of the box. However this task takes care only of backing up the underlaying Orient DB.
You must still assure that you back up your Nexus ${data_dir} around the same time you run the mentioned scheduled task. The same goes for your blob stores. Preferably during off-office hours. Notice that DB stores pointers to the blob stores.
The easiest way is to do the classic backup. If your goal is to perform incremental backup than I assume you will have to choose some strategy for discovering altered files. Perhaps based on file timestamp and thus backing up only those.
Please bear in mind my assumption above may be wrong. I wanted to point out just my idea on how to solve your problem.
