Hi Tim H,
I have an external USB drive
Is it spinning rust, which could be slow to spin up, perhaps more so if
all power comes from USB?
Old style spinney disk with single usb Lead connected to the (powered)
docking station
[E] Can't find snapshots folder.
If it is on a removable drive, please plug it in.
Waiting 30 seconds.
What happens after it waits thirty seconds for the already-mounted
drive?
Is there anything in the kernel's ring buffer around that time?
sudo -i dmesg -Hx
The backup failed again tonight, ran the above command which did not
list anything relevant for the time that the backup ran (all UFW Block
entries)
If I check my backup drive it says it is mounted and if I open the
drive (clicking the icon on the desktop) it will display the folders
and start the backup
So the back-up program starts without intervention. Instead of clicking
on the icon, because who knows what that's doing, do something simpler
like
ls /media/backup/.../snapshots
In the 30 seconds it gives you to "reconnect" the drive I ran the above
command which gave the following
mit@NX1:~$ ls /media/backup/backintime/NX1/root/1/last_snapshot/
backup config fileinfo.bz2 info takesnapshot.log.bz2
The backup then started.
I will have to leave the 30 second warning and do nothing to see what
happens, but I think it just fails to run based on previous error I have
seen when it has not run
Any suggestion
dmesg is your best next step, I'd have thought.
Will investigate
Do you need the drive mounted all the time? Could a cron job mount the
drive a minute before the scheduled backup and unmount it when it's
bound to have finished? The theory being the just-mounted drive will be
up and running and ready to respond, not sleeping to save power.
As it only does the backups I guess i Could try mounting prior to the
backup running. But it does not seem to be a mounting issue more
something linked to letting the rest of the OS know it is mounted.
Thanks for the input
Tim H
