I have used fsck to clear many errors on my backup volume after a crash
during a power failure (see
http://sourceforge.net/mailarchive/forum.php?thread_id=25989686&forum_id=503).
The system is back up, and the web GUI seems to be working normally.
How can I verify the integrity of the backups without doing a full
restore and compare, for which I simply do not have the disk space?
I've just re-read the FAQs and Docs and it seems like the combination of
BackupPC_link, BackupPC_trashClean and BackupPC_nightly *might* do
enough checking to do the trick. The next closest thing was
BackupPC_compressPool, but I already am running with cpool and it
specifically says "there must be no existing compressed backups when you
run BackupPC_compressPool."
I'd rather not just clear the entire thing and start from scratch again
because I have backups going back many months and would hate to lose
that history. But after fsck "fixed" all the stuff it did, I am worried
that the pool has been corrupted and worse that it will CONTINUE to be
corrupted as BackupPC assumes all is well and continues to hard link to
crap instead of what it thinks it has.
For example, should there be directories below cpool/x/y/z? No other
container in cpool seems to have them except the one that had most of
the fsck errors. This seems like a Bad Thing:
/data/backuppc/cpool# find 1/9/4 -type d
1/9/4
1/9/4/1948594ab2b81e13ebeb08e4568cb7a8

What happens if I 'rm -rf /data/backuppc/cpool/1/9/4'?
Thanks,
JP

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
