Snapshots
Home Directories
A snapshot of your home directory is periodically taken.
At a terminal prompt, type:
cd .snapshot
If you type:
ls
You will see a list of directories:
./ hourly.1/ hourly.4/ nightly.1/ nightly.4/ weekly.1/
../ hourly.2/ hourly.5/ nightly.2/ nightly.5/ weekly.2/
hourly.0/ hourly.3/ nightly.0/ nightly.3/ weekly.0/
hourly.0 contains the most recent backup.
Search through the directory to find your lost or deleted file.
When you are finished, you can copy it to your current home directory by typing:
cp file /my/home/directory
E-mail
A snapshot of your e-mail is also taken periodically
At a terminal prompt, type:
cd /var/bak/mail
If you type:
ls
You will see a list of directories:
./ hourly.1/ hourly.4/ nightly.1/ nightly.4/ weekly.1/
../ hourly.2/ hourly.5/ nightly.2/ nightly.5/ weekly.2/
hourly.0/ hourly.3/ nightly.0/ nightly.3/ weekly.0/
hourly.0 contains the most recent backup.
The backup of your e-mail is in the form username.gz ,
where username is substituted with your username.
Search through the directories to find which e-mail backup you want to restore.
To compare the dates and sizes of the backups type:
find . -name username.gz -ls
To restore your e-mail:
cd into the directory you want to restore your mail from
Type:
cp username.gz /var/mail
gunzip /var/mail/username.gz
You will receive a warning:
gunzip: /var/mail/username already exists; do you wish to overwrite (y or n)?
Type y to accept.
Your e-mail has been restored. |
