I'm experimenting with taking snapshots of a linux system (I'm using Antix for the purpose). Everything seems to work, except that SAGE is not copied over faithfully. A few hundred files and about 20 folders are missing, but SAGE being so gigantic, I can't pinpoint exactly which. I'm not 100% sure how the snapshot is made, but as far as I know, the system uses rsync to make a copy of the filesystem. Is there anybody knowledgeable in this matter who could clarify what could be the reason that SAGE is somehow more difficult to copy than other folders?
When I try to start SAGE from the reinstalled snapshot, it results in the following crash-report:
