Remote data storage on S3
Closed this issue · 1 comments
I am wondering if anyone has any experience (or can provide some insight) into the feasibility or best deployment scenario by which all email messages could be stored automatically on Amazon S3. More specifically, if one were to spin up an EC2 server and map an S3 account to a drive/folder and then ran Larch to migrate messages.... Would this represent a problem?
Ideal situation would be to have the indexes on the EC2 server for quick access but then have all the actual emails on Amazon EC2 (objective is to create an archive). BTW - I am guessing that by using this approach IMAP connections to the index would be quick but individual retrieval of individual messages would be slow... Any insight or feedback would be greatly appreciated.
I am doing basically this, using Dovecot on an EC2 server to manage the email archive using native IMAP, and larch to copy from my live email service (Tuffmail IMAP) to Dovecot periodically.
I start the EC2 server when I want to do a backup or retrieval, and stop (but not terminate) it when I'm done, to save on CPU cost.
