I have saved thousands of texts, chat logs, email for many years
When I changed phone I made a backup of all texts onto my memory card or emailed the log file to myself. I have every text since 2011. Total exchanged texts = 50,000
When I used to chat on MSN messenger and after every chat log got full, I would put it on my backup harddrive. I have every chat log with every online friend from 2004-2012. Total size of files that consist only of text = 149MB
I have every email saved since 2001 but that is just passive since if you do not delete emails they just stay there.
My best friend jokes that I am a creep for saving such stuff. It is not like I ever read them in my spare time
But lately I have realized I live too much in the past which is why I wanted to bring this up
PS: Backing up any of the above is effortless. In my entire life I must have spent not more than a total of 10 minutes backing any and all of it up
