Hello,
when I store scientific articles and select the title of the article as the file, it happens, that there is a line break in the name of the file. The filename attached contains that special character (if the SF system doesn't replace it).
Such files appear split in TMP.all.files and tar just hangs with 100% CPU load when processing the file with the -T option.
As a workaround, I start backup2l, and verify if there is a progress observing the size of the TMP.all.tar.gz. If the size remains the same, I either look directly into TMP.all.files for names w/o path (which can be tedious) or I run
tar czf TMP.all1.tar.gz -v -T TMP.all.files --no-recursion
(thus in verbose mode) for getting the last file processed by tar. Then I correct the file names and start again.
