Please tell me that virusses and bacteria can't be revived after 30k years in ice, or that our imune system is able to remember its defenses against virusses and bacteria it hasn't seen for 30k years.

The Saarland University has a (pretty small) botanical garden that is open to the public.
https://en.wikipedia.org/wiki/Botanischer_Garten_der_Univers... says it closed April 1, 2016. More details (in German) at http://www.uni-saarland.de/nc/aktuelles/artikel/nr/14351.htm... .

If the DNA in a seed is still in good enough shape to support blooming after being frozen 30,000 years, perhaps a seed frozen in a meteorite [1] could also survive long enough to be spread between solar systems. [1] maybe after glancing off a planet or created by the collision of two large objects
Could survive long enough to be toasted when the meteorite finally falls to the promised land planet, in form of fireball.
When talking about megafauna resurrection, it is often said that it's not possible because DNA degrades too much after a few thousand years. Yet apparently the DNA of this plant was still viable. What am I missing?
(Remember that if you have multiple cells, you have lots of strands of the same DNA, all broken in different places.)
But I'm not an expert.

Our immune system is pretty good at identifying all kinds of foreign proteins. Unless a virus or bacterium has specifically evolved to evade our immune system, its chances are pretty bad. I wouldn't be too worried.
Every day we inch one step closer to bringing back dinosaurs, thus making Jurassic Park a reality.

This is one of the fears with global warming, that a virus trapped in ice may be thawed and we would be vulnerable to it.
There's also a surprising number of Nazi secret bases.

Perhaps plant DNA is hardier against time, bacteria, freeze/thaw cycles, etc than animal DNA? I'm not a biologist, so I'd also love to know.
Is the same problem as to restore a file that is partially distroyed in four or five points. You can still recover the original file if you have five copies, each one with the damage in a different area. Polyploid organisms have several identical security copies of each chromosome. If something in a chromosome is damaged, they can quickly fix the damaged areas using the safety copy saved in his 'twin' chromosome.
