Cold Storage

[parMaster]

So I have an external HDD connected to one of the servers an I copy recordings there for redundancy (third backup). It would be nice to automate this process. Initial thoughts:

• define some kind of "cold storage" path in config, probably in "commander" section, so it's just "copy and forget" process, without any downloading
• FIFO type of eviction strategy - delete latest if there's no space for the new files
• evict as many "days" (since the recordings grouped in yyyy-mm-dd folders) as needed to make space for new files (any fail-safes??)
• CLI tool running regularly
• should it look into DB or be like some kind of "special type of rsync"?
• cold storage can be either bigger or smaller that the primary repository storage device and use the whole allocated space - either it's 10% or 400% of the main storage
