Topic: YAY for gjournal (_8 stable) and rsync (bwlimit) YMMV
Both of which together restored functionality/confidence (so far, 3 days) using
rsync (bwlimit parameter) to backup to sata-on-pci using TX4 which was
unstable using other methods /rsnapshot/ for example on plain UFS2.
(details on the bsd forum,
tailed onto a thread there,
keyword search bwlimit,
no time to post here, also I could leave something out inadvertantly. )
YMMV but I wish I had known this years ago (should gjournalling have
been available then.) (and if it works as reliably during the next years).
