+
+Difficulty: private networking between hosts

+	     
+	     Should be possible to switch IPs

+Vraag uitgezet bij Allan voor meer informatie.
+Allan: het komt al 1.5 maand voor; https://group-onecom.slack.com/archives/C02FT9KEFNH/p1729863978525299
+
+Uit dat bericht blijkt dat Jerry zou kijken of het Acronis is.
+
+Jeroen gecontacteerd om ff te vragen of ze dat al gedaan hebben; jeroen denkt dat het niet door Acronis komt omdat dat vooral read ops zijn en verspreid over de nacht.
+
+Allan stuurt graph met kantteking: "seems to involve alot of LUNs": `https://prometheus2.env.vps1-cph8.one.com/graph?g0.expr=count(lun_write_ops%20%3E%20(lun_write_ops%20offset%2020m%20%2B%20100))&g0.tab=0&g0.display_mode=lines&g0.show_exemplars=0&g0.range_input=30m&g0.end_input=2024-12-05%2005%3A47%3A35&g0.moment_input=2024-12-05%2005%3A47%3A35`

+Jeroen dacht mogelijk mysql dumps van shared, maar zou ook verspreid moeten zijn: ging kijken wanneer die gdraaid hadden, niks meer over gehoord.

+O.b.v LUN graph heb ik wat LUNs gepakt en bleek allemaal managed vps te zijn; Jeroen op onderzoek naar wat daar binnen rond die tijd gebeurd. Verdenkt PSA crons.

+I need to become more goal-oriented: set a clear goal with a clear end and work towards that.
+I'm currently working to improve my skill in note-taking to help achieve current and determine new goals.
+I'm doing this by setting up a "second brain" using ideas from the book "Building a second brain" by Tiago Forte.
+
+---
+
+**General Performance and Achievements**  
+	Describe your overall performance throughout the year and highlight any achievements you are especially proud of
+
+Looking back I feel that my focus this year has been impacted due to a series of events happening outside of work in my private life, such as moving to a new house and the death of a close friend. Besides that I feel I was often doubting myself which made me indecisive at times.
+
+The backup service which I had mostly worked on developed far slower than I liked. Due to above but also because so many parts of this were completely new to me. I think that I could have done a better job at learning each of them by separating it into smaller "toy" projects and learning each part before putting it together. For example how libraries such as oslo.messaging and taskflow worked. Besides that I also feel I didn't always do a great job on including the rest of the team.
+During the last quarter of this year I did feel I was able to improve and work with a clearer mind and work more closely together with Erik; communicating more frequently and effectively, especially with the snapshots.
+
+I feel proud that, even though it was not progressing as quickly or organized as I liked, I was able to set-up the backup service and put it to production and seeing few operational problems as of yet. I feel especially proud of how we were able to utilize the project to quickly implement the snapshot feature that was suddenly requested.
+
+**Opportunities to become even better**
+	Which areas do you perceive as your strongest?
+
+I think I'm always eager to develop a deep understanding of how things technically work, abstract thinking, I have a sense of responsibility and am always prepared to help out where needed.
+
+	Which areas would you like to improve in?
+
+I am currently trying to improve my productivity by setting up a note taking system. I will continue trying to improve this. I plan to also do a little self "performance review" at the end of each week to help me keep track of things happening during the year.
+
+I think in a broad sense I need to become better at setting clear goals that have a clear end which I can work toward. Both in work related things such as projects, but also in personal things such as setting up a note taking system.
