将图像从 ArangoDB 的文件系统传输到 amazon s3

Question

I am currently using ArangoDB to store all the data I'm using for my application, including images. Now I want to migrate to S3 to store the image files and transfer the files I currently have in my ArangoDB.

I am aware that images are stored in file system, but I am not sure how to actually transfer them to s3.

Thank you for your help

The location of the data files is implementation-specific, as it can be changed at install and startup. On Linux, the default directory is /var/lib/arangodb3 .

But in my experience, backing-up the raw storage files is not a good idea. I have found it very difficult to restore or access data with this method. Instead, I recommend using one of these two "official" methods:

1. Hot backups (enterprise-edition only)
2. JSON export (usingarangobackup /arangoimport )

Snapshot-style "Hot backups" are really great - truly the preferred method. They have everything you would need (speed, reliability, portability, etc.), with only a few case-dependent limitations . The real downside is that it's only available in the enterprise editions (including Oasis ).

JSON export is the "thrifty" backup option - I would forget about arangorestore (it does horrible things to your _id/_key values, and takes forever to do so). The good news about JSON export is that it's EXTREMELY portable. Almost ANY code-base (and even most good DB's) can work with it, so you're never locked into a single product or workflow, or even a specific version of ArangoDB (making up/down-grades much easier).
