Backup problem on 10.20

[Jeff Tolly]

Have a daily cron job running and have included the text from there concerning the backups.

What happens is that a dump of the actual backup is written to file within our /home/fbackupfiles inconsistently

When this happens our /home volume is at 100% utilization due to the volume only being 63MB's. Usually the /home is around 12% utilization.

Not sure why this file gets created and any thoughts to why?

Thought I would add a line to the cron to delete this but would like to figure out why it happens here and there?

Thank you

The key to understanding your problem is not the crontab but rather the script that is invoked. You really need to look at /home/fbackupfiles/fullback for the answer. It's also rather unusual to invoke a cronjob in the background (&). Note that the logs are always appended so that if not truncated periodically then filling up the filesystem is guaranteed to happen.

1) Run this backup command manually and see what happens. Post the errors you get

2) What type of backup are you doing? (tar, cpio, fbackup etc).

3) Check the file type and content of dump file with 'file' or 'strings' command.

4) Redirect the log files to another file system which has enough space available.

Well, I assume this is just a typo, but to be sure...

on the monday backup line, there's no weekday field for the cron. it just says

15 1 * * /usr....

This might cause problems.

Probably just a typo in your message though.

Hi
a common probel is a typo

om intead of 0m (Oh M instrad of Zero M)

Check out your backup script for device name.

Using om (OH m) will push the backup to a file instrad of the device 0m (Zero m).

Corrected typos - Been a long day.

Hi

om instead of 0m (Oh M instead of Zero M)

Check out your backup script for device name.

Using om (OH m) will push the backup to a file instead of the device 0m (Zero m).
