backup #19

Backup rsnapshot process verify

Check on backup (rsnapshot) status on 'pretoria' and 'capetown'.

NicolasRannou commented 9 years ago

Debug steps:

// log in
ssh root@capetown
// check cronjobs
cat /etc/cron.d/rsnapshot
// run a test daily backup
/usr/bin/rsnapshot -t daily

The last command doesn't return any error, just the commands to be executed.

So I took 1 step back, by checking the content of the /backup directory

[root@capetown:x86_64-Linux]/#>ls -als /backup/
total 52

Date stamps are OK, which means the backup runs. What is not good is that those directories are empty whereas it should contain the research, sys and arch directories. (see above output of test command "/usr/bin/rsnapshot -t daily")

/usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \
    --rsh=/usr/bin/ssh root@tautona:/neuro/labs/grantlab/research \
    /backup/daily.0/tautona/ 
/usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \
    --rsh=/usr/bin/ssh root@tautona:/neuro/sys /backup/daily.0/tautona/ 
/usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \
    --rsh=/usr/bin/ssh root@tautona:/neuro/arch /backup/daily.0/tautona/ 
touch /backup/daily.0/

Next step is to run one of these command to see what is going on.

/usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \
    --rsh=/usr/bin/ssh root@tautona:/neuro/arch /backup/daily.0/tautona/

Returns: 

root@tautona's password:

Passwordless ssh connection between capetown and tautona was down. After entering the password by end, it seems to work. (currently running). Will fix the passwordless ssh issue as soon as the backup of arch dir is completed.

Stopped the manual backup as it would still be running when people come in the office (slow network then).

rudolphpienaar commented 9 years ago

wonderful! let's verify it works tomorrow and then we can close.
