# Tahoe-LAFS Reliability Tool

Given certain assumptions, this page calculates probability of share loss over time, to help make informed decisions about how much redundancy and repair bandwidth to configure on a Tahoe-LAFS grid.

## Simulation Results

At the end of the report span (elapsed time ), the simulated file had the following properties:

- Probability of loss (no maintenance):
- Probability of loss (with maintenance):
- Average repair frequency: once every secs
- Average shares generated per repair:

This table shows how the following properties change over time:

- P_repair: the chance that a repair was performed in the most recent check period.
- P_dead (unmaintained): the chance that the file will be unrecoverable without periodic check+repair
- P_dead (maintained): the chance that the file will be unrecoverable even with periodic check+repair

t | P_repair | P_dead (unmaintained) | P_dead (maintained)
