 |
|
I found some threads on this forum, which have gotten me this far. I had it working but then I tried to add the date to the filename, and now Tar is angry.
| Code: |
cron.daily # cat backup.cron
#!/bin/bash
#
# Backup Script
TARGET='server-$(date +%Y%m%d).tgz'
DIRS='/etc/ /var/www/localhost/htdocs/ /var/bind/ /home/'
EXCL='/etc/backup.excl'
cd /share/backup
tar cvpzf $TARGET -X $EXCL $DIRS >> /var/log/backup$(date +%Y%m%d).log
find . -mtime +7 -exec rm {} \;
emerge -pev world > /share/backup/emerge.list
|
| Code: |
etc # cat backup.excl
/var/www/localhost/htdocs/pics/*
/var/www/localhost/htdocs/cdlist/*
/var/www/localhost/htdocs/dvdlist/*
/var/www/localhost/htdocs/manual/*
/var/www/localhost/htdocs/cdlist/*
|
Error:
| Code: |
./backup.cron: line 5: +%Y%m%d).tgz: command not found
|
[/code] |

Try to put backqoutes around the date command:
server-`date +%Y%m%d`.tgz

Thanks, tried that, double-quotes too. I have the same config on pipe to the backup log, and that works. |

Maybe that?
I think you probably need quotes around the whole thing, as otherwise tar will freak out at the space. Actually, it's freaking out at the $(...) bit because otherwise it wouldn't care about the space...
Maybe if you find out the date earlier in the script and export it to a variable then put that variable in? Then you won't need any spaces or anything.

I tried that too, but the space is still there when the command is executed, because the variable expands to whatever its definition. At this point, I'm considering using logrotate to deal with my backup file  |
