Unfortunatelly restic prune downloads a lot of data to rewrite data packs that are going to stay on server after prune operation. You should do restic prune from time to time to ensure old snapshots removal (we want to save space and money right?).

You may think why should I bother with a download price, you will do it only in case of data loss right? The realityĪ year of incremental backups of 100GB data won't use 100GB but much more space.ġTB, maybe more depends how much redundancy in data do you have and how often you would like to create snapshots. Months * data_in_GB * storage_price = yearly_backup_priceīut that is not true for real backup scenarios. The first impressionĬalculations based on may lead you to this equation (let say you got 100GB of data): (at least in my case where I have around 60GB and want to remove a snapshot with accidentally added files). It's just cheaper to run a new backup and delete the old one. This may/will result in massive download for (as I think) packs rewritting (I've downloaded 6GB, made around 34k Class B Transactions and give up with progress around 17%). Will delete 1055 packs and rewrite 6590 packs, this frees 27.166 GiB Processed 897977 blobs: 267 duplicate blobs, 443.513 MiB duplicateįind data that is still in use for 2 snapshotsįound 861259 of 897977 data blobs still in use, removing 36718 blobs Repository contains 13521 packs ( 897977 blobs ) with 62.648 GiB What is more, with B2 pricing there is no point in running restic prune (as you may see I give up after 1.5 hour). It's cheap but not free.įortunatelly restic nearly doesn't use 'Class C Transactions' but 'Class B' is used a lot during restic check (which you may/should run after each backup). Next (0.8.4+) restic release with 'smart caching' should fix it.īrowsing files stored on your B2 (using 'Browse Files' option) is counted to the downloads quota. Unfortunatelly currently Restic makes a lot of 'Class B Transactions' calls during restic check execution (which may be both costly and time consuming) see issue#1696.

Uploading is free and storage is really cheap (or event cheapest ATM), but there are some other (more or less) hidden charges like 'Class B Transactions' and 'Class C Transactions'. It's cheap, but definitely not as cheap as you may think. You may think that BackBlaze B2 and restic will guarantee you nearly free cloud backup.

Install Restic on Mac OS X (with Homebrew):

When your cloud storage space is ready it's time to install and initialize Restic repository. They will be required for the next steps so copy and paste them somewhere or just leave them open.Īfter closing credentials popup you won't be able to view Application Key you will have to generate a new one. You should easily find large 'Create a Bucket' button after logging in to your account (which is also visible on the next screenshot).īucket name has to be globally unique so you would probably end up with prefixing it with your account name or something similar.Ĭheck your Backblaze B2 credentials using link 'Show Account ID and Application Key'. Let's start with Backblaze B2 as you will need some cheap cloud storage. This tutorial was made on Mac OS X High Sierra with restic 0.8.3 (which may or may not be relevant to you).Įxample shell script is available at the end of this post.
