Hi i am trying to figure out if i can ditch Garage and just use ZeroFS for geo distributed storage. I wan to bale to find info about the importance of the SlateDB cache. If i loose the cache or it gets corrupted without me having any backup, do i loose the data that ZeroFS manages? Should i also backup the cache? |

Hi, It's completely safe to discard. ZeroFS doesn't any write-back caching, writes are durable on object storage when fsync returns (with 9p and nbd, nfs is more complicated). |

Ah i see, glad to hear that. One more thing is it ok if multiple zerofs instances are using same cache folder? |
Yes, it's fine, because ZeroFS creates a unique ID per bucket that it uses as a sub-cache folder per instance |
