But why? Taken slightly out of context, it reminds me of this:
“Only wimps use tape backup. REAL men just upload their important stuff on ftp and let the rest of the world mirror it.”
(note: he wasn't talking about wallets)Unless you're restricted on bandwidth or RAM, I wouldn't worry about backing up blockchain data as long as thousands of nodes have a backup online!
It's not only the bandwidth restrictions, but, isn't it also a pain when you need to wait 3 days to have a fully functional node up & running again?
2. Compute and store checksum for each files. It should be much faster than asking Bitcoin Core to perform reindex if you also worry about file corruption/integrity.
Can you elaborate on this please? Computing and storing checksums will certainly help with integrity, but how will they help in speed?
3. If you wish to reduce storage usage on your HDD, compress entire ~/.bitcoin/ directory. I remember old thread that discuss it could reduce the size by about 20%, although i can't find the thread.
Yeah, that's cool. I could also add an encryption password on the compressed file, instead of messing with encrypting the entire disk which takes time. So, one layer of encryption on the .tar file, another on the wallets themselves.
