I just had to upgrade the storage of my snapshot server again and thought this is a good opportunity to give a short update about the current state of engine snapshots.
If you are curious how the process of creating engine snapshots works, please check out the previous post over here.
I have given the last update about engine snapshots just about 5 months ago on September 25. Back then an engine FULL node snapshot had roughly 60GB in size.
Right now (on February 26) the size of full node snapshots is roughly 82GB, which means the snapshot grew ~22GB in the last 5 months. This would account to about 150MB the snapshot grew every single day on average.
If we have a look at the chart we can see that it is growing almost linearly:
But if we have a closer look at the following chart, we can see, that activity on the engine sidechain did actually increase a bit in the last few months, compared to the previous year, with a bit of a down at the beginning of the year. The chart shows the daily increase in the snapshot size, with a few outliers, when the snapshot script failed for a day:
LIGHT node snapshots on the other hand had just about 4.5GB on September 25. Keep in mind that light node snapshots don't really grow much, but are fluctuating around that size, depending on how much the engine sidechain is used on a given day, as they only store about 30 days of history.
Today (on February 26) the size of light node snapshots is around 5.3GB, which does also amount in a slight increase (in activity also). The chart confirms our observation:
The big hole in the middle was when I had to rebuild the light node history, as I messed up the backup node (and the one at the start when I initially built up the 30 day history).
The chart again nicely shows, how the engine sidechain activity increased at the end of 2022, then dropped at the start of 2023 and now seems to be at an all time (activity) high again.
This is also shown in the chart with the daily increase / decrease of the light node snapshot size in MB:
The large blue areas at the start and in the middle are again the build up of the history at the start and when I had to rebuild it.
That's all stats I've got for the moment. I will be giving an update again in a few months time. For now, the storage upgrade went well and I should be good for the next few months.
