17 All the data I have on my laptop is either:
19 * Version Controlled
20 * Rsync'd from a server
21 * Not important
23 My laptop doesn't have an SSD, but it's old and probably about ready to
24 die in general. All of my documents are version controlled - git - and
25 therefore "automatically" backed up. I rsync other files around, like my
26 music and some software, so that's all backed up as well.

34 afaik tar and rsync should continue to work for SSDs. The more places
35 the data is in, the better. If you regularly rsync text (say /etc), I
36 would consider version control.
