[Duplicity-talk] My Incremental and Full Scripts

[Jon]

Hi All,

I'm not sure how useful this is, but since there seems to be repeated 
questions about the best way to set up full and incremental backups, I 
thought I would post the scripts I use.

I'm not saying that my way is the best way, just that it is a way and 
I've been using it for several months. I've done periodic test restores 
and they always work, so I feel good about the setup.

I run two scripts: a full and an incremental script. I run the full each 
 Sunday night at 11PM and the incremental every other night at 11pm.

I keep 14 days of backups, I backup Thunderbird's IMAP email, and my 
backup server runs SSH on a non-standard port.

You'll need to change anything munged, localuser to be a local user on 
your machine, localmachine to your host name (optional), 
admin.server.com to your own backup server, and probably the SSH port 
(not required at all if you're running SSH on port 22). These scripts 
logs all their actions as well as report the available disk space at the 
end of the backups and emails the reports to me locally just for good 
measure. I don't always notice if a backup report isn't present, but I 
have become accustomed to getting the daily backup emails and I notice 
if they're missing. The incremental also includes collection status 
reports in the report.

Hope these are useful for someone.

Here's the full backup script (watch for wrap/formatting errors):

#!/bin/sh
# Export the PASSPHRASE variable
export PASSPHRASE=munged

# Get the date
repDate=`date +%Y%m%d`;

# Cleanup first (anything older than 21 days)
/usr/bin/duplicity remove-older-than 14D -v9 --force 
scp://address@hidden:2035//backup

# Now do the backup
/usr/bin/duplicity full --include /home/localuser/Documents --include 
/home/localuser/.mozilla-thunderbird/01pvkqct.default/ImapMail/mail.messagingengine.com 
--include /home/localuser/scripts --exclude '**' /home/localuser/ 
scp://address@hidden:2035//backup/localmachine --sign-key MUNGED 
> 
/home/localuser/Documents/BackupLogs/Full_Backup_Log_$repDate_localmachine_admin.log

# Get the disk space
echo "Availble Disk Space on Server" >> 
/home/localuser/Documents/BackupLogs/Full_Backup_Log_$repDate_localmachine_admin.log
echo >> 
/home/localuser/Documents/BackupLogs/Full_Backup_Log_$repDate_localmachine_admin.log 

/usr/bin/ssh -p2035 address@hidden df -h >> 
/home/localuser/Documents/BackupLogs/Full_Backup_Log_$repDate_localmachine_admin.log

# Mail me the results
mail -t localuser -s "localmachine Backup Full (Admin)" < 
/home/localuser/Documents/BackupLogs/Full_Backup_Log_$repDate_localmachine_admin.log

And the incremental script (same

#!/bin/sh
# Export the PASSPHRASE variable
export PASSPHRASE=munged

# Get the date
repDate=`date +%Y%m%d`;

# Cleanup first (anything older than 21 days)
/usr/bin/duplicity remove-older-than 14D -v9 --force 
scp://address@hidden:2035//backup/localmachine

# Now do the backup
/usr/bin/duplicity --include /home/localuser/Documents --include 
/home/localuser/.mozilla-thunderbird/01pvkqct.default/ImapMail/mail.messagingengine.com 
--include /home/localuser/scripts --exclude '**' /home/localuser/ 
scp://address@hidden:2035//backup/localmachine --sign-key MUNGED 
> 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log

# Get list of backups
/usr/bin/duplicity collection-status 
scp://address@hidden:2035//backup/localmachine >> 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log

# Get the disk space
echo "\nAvailble Disk Space on Server" >> 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log
echo >> 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log 

/usr/bin/ssh -p2035 address@hidden df -h >> 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log

# Mail me the results
mail -t localuser -s "localmachine Backup Incremental (Admin)" < 
/home/localuser/Documents/BackupLogs/Incremental_Backup_Log_${repDate}_localmachine_admin.log
