How can I backup all content of the server, then restore in another maschine?czsanThu, 16 Oct 2014 02:56:48 -0500http://ask.sagemath.org/question/24494/save command in SAGEhttp://ask.sagemath.org/question/10496/save-command-in-sage/I'm trying to save a 'big' rational matrix in SAGE, but I'm running into problems.
After computing my matrix A, which has size 5 x 10,000 and each entry contains rational numbers in fraction form with total number of digits for numerator and denominator more than 10 pages, I run the following command:
save(A, DATA + 'A').
This gives me the following error message:
Traceback(most recent call last):
...
RuntimeError: Segmentation fault.
After this, I can't access A at all any more. In other words, when I try to compute say A[2,3], I get an error. However, before running the save command I was able to compute this entry. Also, I tried the same save command with a 'smaller' matrix and that worked fine. I should also note that I'm using a laptop with 64-bit operating system, x64-based processor, Windows 8, i7 CPU @ 2.40 GHz and 8 GB RAM. Let me know if you need further information. My questions are:
1. Why can't I save my matrix? Why do I get the above error message? What does it mean?
2. How can I save my matrix A? Is there any other way I can save it?Sandi XhumariSun, 01 Sep 2013 11:07:15 -0500http://ask.sagemath.org/question/10496/Sage installation administrationhttp://ask.sagemath.org/question/9936/sage-installation-administration/Hello there,
Not sure if I am looking at the right place for documentation, but I am not able to find much documentation on sage system installation administration. Most of the documentation I can find talks about using sage and installing them. What about for administration of the installation? The following questions come to mind:
1. Where are the user password on one sage installation stored? Can that password be shared across multiple sage installation on a same local area network? How are they administered?
2. How do you perform a backup on a sage installation? Just make a copy of all the files in .sage directory? [ for default installation where everything points to .sage directory]
Where can I find documentation on topics more towards the administration of sage installation than using sage?
thanks
