I remember when you could store summon items in the bank and it would be there the next day varent fixed that, But you can store it on your corpse until looted or expires. Back in the old days I use to be a real Item pig or after a long night raid and we didn't want to divide up the loot until the tomorrow. I would log in a mule load him up and get guard whack and repeat until you finished storing. It would be there in the summoned bags the next day ( or week if not logged in) ( warning server patches can some times do a corpse clean up )
Don't leave anything in it when you log off. the Backpack, and all contents poof when you camp. There is a 30 minute delay, so if you go linkdead, and get back on, it's still there.
The Glowing Backpack turns into a Huge Disenchanted Backpack if you camp off and happen to have gear in the bags. Or at least it does as of now on the Progression Server: Lockjaw.
I found a Glowing Backpack in WestCommons I was wondering where to get several more! So the question is who gets the spell to summom this and where can I find them!
