A simple backup solution. Nice backup formats (tarballs) and the ability to restore when it all goes wrong.
Amanda is in the standard ubuntu repository.
apt install amanda-server apt install amanda-client
As part of the install a user is created for the service to run under in Ubuntu's case this is "backup" remember that for later.
Now we need to set up some directories.
mkdir -p /opt/amanda/holding mkdir -p /opt/amanda/state mkdir -p /opt/amanda/state/{curinfo,log,index} <--- creates all the sub directories mkdir -p /etc/amanda/solaris_bs1 <--- This is the name of the profile we will call.
Create Tape locations
mkdir -p /srv/backup/vtapes/slot1 mkdir -p /srv/backup/vtapes/slot2 mkdir -p /srv/backup/vtapes/slot3 mkdir -p /srv/backup/vtapes/slot4 mkdir -p /srv/backup/vtapes/slot5
Now add an amanda.conf file.
nano /etc/amanda/solaris_bs1/amanda.conf
org "solaris_bs1" infofile "/opt/amanda/state/curinfo" logdir "/opt/amanda/state/log" indexdir "/opt/amanda/state/index" dumpuser "backup" mailer "/usr/bin/mail" mailto "mark@scottworld.net" tpchanger "chg-disk:/srv/backup/vtapes" labelstr "MyData[1-5][1-5]" autolabel "MyData%%" EMPTY VOLUME_ERROR tapecycle 4 dumpcycle 3 days amrecover_changer "changer" tapetype "TEST-TAPE" define tapetype TEST-TAPE { length 100 mbytes filemark 4 kbytes } define dumptype simple-gnutar-local { auth "local" compress none program "GNUTAR" } holdingdisk hd1 { directory "/opt/amanda/holding" use 50 mbytes chunksize 1 mbyte }
Now lets create a disklist (which is used to define what gets backup up)
nano /etc/amanda/solaris_bs1/disklist
Add the contents of the backup
localhost /path/share/to/backup simple-gnutar-local
Grant the backup user permissions on these folders / files
chown backup /opt/amanda -R chown backup /etc/amanda -R chown backup /srv/backup -R chmod 755 /opt/amanda -R chmod 755 /etc/amanda -R chmod 755 /srv/backup -R
You need to allow tar to run by amanda and set its path for Ubuntu.
Edit
nano /etc/amanda-security.conf
Uncomment and fix
runtar:gnutar_path=/usr/bin/tar
Do some checks...after becoming backup
sudo -s -u backup amcheck solaris_bs1
You should get a nice readout of any errors...
Amanda Tape Server Host Check ----------------------------- NOTE: tapelist file does not exists it will be created on the next run NOTE: Holding disk '/opt/amanda/holding': 442355712 KB disk space available, using 51200 KB as requested slot 1: contains an empty volume Will write label 'MyData01' to new volume in slot 1. NOTE: skipping tape-writable test NOTE: host info dir '/opt/amanda/state/curinfo/localhost' does not exist It will be created on the next run NOTE: index dir '/opt/amanda/state/index/localhost' does not exist it will be created on the next run Server check took 0.168 seconds Amanda Backup Client Hosts Check -------------------------------- Client check: 1 host checked in 2.342 seconds. 0 problems found. (brought to you by Amanda 3.5.1)
Try a backup
amdump solaris_bs1
Check it...
echo $?
If you have a 0 then there is no issue.
0
You can get a nice report..
amreport solaris_bs1
You can then cron these,
nano /etc/cron.d/amanda
0 18 * * * backup /usr/sbin/amcheck -m solaris_bs1 15 3 * * * backup /usr/sbin/amdump solaris_bs1
We can now add more locations to backup Add the backup user to the sambausers group.
usermod -a -G sambausers backup
Now edit disklist and update the file with more shares add to the backup job (remember the "backup" user must have READ access to back up the target files.)
nano /etc/amanda/solaris_bs1/disklist
localhost /etc simple-gnutar-local localhost /opt simple-gnutar-local localhost /srv/media/music simple-gnutar-local localhost /srv/media/photos simple-gnutar-local localhost /srv/data/documents simple-gnutar-local localhost /srv/data/www simple-gnutar-local localhost /srv/data/scottcloud simple-gnutar-local localhost /srv/data/mysql simple-gnutar-local
