@ -5,7 +5,7 @@ description: Instructions for pruning a Geth node
<Note>Offline pruning is only for the hash-based state scheme. Soon, we will have a path-based state scheme which enables the pruning by default. Once the hash-based state scheme is no longer supported, offline pruning will be deprecated.</Note>
A snap-sync'd Geth node currently requires more than 650 GB of disk space to store the historic blockchain data. With default cache size the database grows by about 14 GB/week. This means that Geth users will rapidly run out of space on 1TB hard drives. To solve this problem without needing to purchase additional hardware, Geth can be pruned. Pruning is the process of erasing older data to save disk space. Since Geth `v1.10`, users have been able to trigger a snapshot offline prune to bring the total storage back down to the original ~650 GB in about 4-5 hours. This has to be done periodically to keep the total disk storage

Pruning is the process of erasing older data to save disk space. Since Geth `v1.10`, users have been able to trigger a snapshot offline prune to bring the total storage back down to the original ~650 GB. The pruning time depends on your hardware but it can take upwards of 12 hours. This has to be done periodically to keep the total disk storage
within the bounds of the local hardware (e.g. every month or so for a 1TB disk).
To prune a Geth node at least 40 GB of free disk space is recommended. This means pruning cannot be used to save a hard drive that has been completely filled. A good rule of thumb is to prune before the node fills ~80% of the available disk space.
