bcapps VS BorgBackup

Just for fun, I created maxdierolls.csv in https://github.com/barrycarter/bcapps/tree/master/ONEOFF/ that shows the results for 1 <= k <= n <= 100

To be fair, I actually do this in https://github.com/barrycarter/bcapps/tree/master/bc-gcdist.pl because it's useful in determining Internet ping times. Roughly speaking, Internet packets rarely travel faster than 0.5c (though I have seen as high as 0.6c)

I never really got anywhere on this, but my work is at https://github.com/barrycarter/bcapps/tree/master/bc-calc-risk-odds.m

The exact chance is 34382839/81839428 or about 42.013%. I used Mathematica and recursion to solve this: https://github.com/barrycarter/bcapps/blob/master/REDDIT/repeat-cards.m

Feel free to take a look at https://github.com/barrycarter/bcapps/tree/master/README-projects.txt but here's a more sinister and useful suggestion that doesn't really answer your question.

Try graph1.csv in https://github.com/barrycarter/bcapps/blob/master/ONEOFF/

My https://github.com/barrycarter/bcapps/tree/master/FINANCES/bc-parse-bank-email.pl probably won't help, but is an example of how you can parse different types of documents (emails from various banks) using a single script

https://github.com/barrycarter/bcapps/tree/master/bc-getmail.pl checks all my email accounts in a neverending loop, handling cases where getmail gets stuck

At one point, I cataloged some PBS strips at https://github.com/barrycarter/bcapps/tree/master/METAWIKI/pbs.txt -- you might find something useful there though it's nowhere near complete

i use - and recommend - "borgbackup": for example with the "vorta" graphical frontend

I used this many, many years ago but switched to Borg[0] about five years ago. Duplicity required full backups with incremental deltas, which meant my backups ended up using too much disk space. Borg lets you prune older backups at will, because of chunk tracking and deduplication there is no such thing as an incremental backup.

Currently, I'm auto-backing it up with borg (push mode) through wireguard tunnel to NAS behind ISP's CGNAT. The borg takes care of deduplication in SQL file, so incremental update (even in append-only mode) is very small for PostgreSQL dump.

Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done).

Does anyone know how Borg 1.x and 2 would compare to Kopia?

You could use borgbackup.
