I have a pile of files, and a personal svn repo totalling around 13GiB |
2 |
which I want to back up to cheaply to 'the cloud'. I would also like |
3 |
it to be non-trivial for someone with access to the cloud servers to |
4 |
decrypt my data. |

|

I have a 50GB free account for Box.net, but would consider others if |
7 |
they have significant advantages. The box.net account is only allowed |
8 |
upload files of max 100MiB at a time. |

Now one problem facing me is that most cloud services don't give |
11 |
assurances of bit parity, so I'd like to be able to recover most of |
12 |
the files if I lost my local copies and there were bits missing from |
13 |
the uploaded backup. This makes the one-big-encrypted-file approach a |
14 |
no-go. |
15 |
|
16 |
My current approach is to use split-tar, with the intention of |
17 |
encrypting each file separately. (Is this worse / equivalent to having |
18 |
one big file with ECB ? ) |

...but this seems to have difficulty sticking below the 100MiB |
21 |
individual file limit (possibly there are too many large files in the |
22 |
svn history). |

Any thoughts? I'm sure that many of you face this problem. |
